The order parameters obtained from the dipolar couplings are used to test a novel Hamiltonian that includes two Maier-Saupe nematic terms plus Kobayashi-McMillan smectic A terms. It is shown that this Hamiltonian can rationalize the NMR experiments with physically reasonable smectic order parameters and Hamiltonian prefactors. (C) 2009 Elsevier B.V. All rights reserved.},

This labeling study indicates that D-2 loss forms the reactive species, ((CyPh) [NPN]Ta)(2)(mu-D)(2), which promotes small molecule activation. Addition of CyPH2 to ((CyPh)[NPN]Ta)(2)(AtD)(4) gives a series of isotopomers, with an average composition of 0.67 H and 1.33 D, supporting a 1,2-H-2 elimination step to form the tantalum phosphinidenes.

Analysis of the spectra indicates that (i) both chemical systems are unusually strongly bound compared to conventional van der Waals complexes, (ii) significant charge rearrangement occurs at the xenon nucleus upon formation of both XeAgF and XeAgCl as shown by the Xe-131 nuclear quadrupole coupling constants and (iii) in both XeAgF and XeAgCl the Xe-Ag distance is small compared to the sum of the Xe van der Waals radius and the Ag+ ionic radius. An ab initio study of the two species has been performed. The combined experimental and theoretical investigations indicate that the Xe-Ag interaction is not easily described, but that there is some evidence for weak chemical bonding.},

It was prepared by laser ablation of Au in the presence of Xe and SF6, and stabilized in a supersonic jet of Ar. The spectrum was measured with a cavity pulsed jet Fourier transform microwave spectrometer, in the frequency range 6-26 GHz. Rotational constants, centrifugal distortion constants, and Xe-131 and 197 Au nuclear quadrupole coupling constants have been evaluated. The molecule is linear, with a short XeAu bond (2.54 Angstrom), and is rigid. The 131 Xe nuclear quadrupole coupling constant (NQCC) is large (-135 MHz). The 197 Au NQCC differs radically from that of uncomplexed AuF. The results are supported by those of ab initio calculations which have given an XeAu dissociation energy similar to100 kj mol(-1), plus Mulliken and natural bond orbital populations, MOLDEN plots of valence orbitals, and an energy density distribution. All evidence is consistent with XeAu covalent bonding in XeAuF.},

	abstract = {Tris(trifluoromethyl)borane carbonyl, (CF3)(3)BCO, is obtained in high yield by the solvolysis of K[B(CF3)(4)] in concentrated sulfuric acid. The in situ hydrolysis of a single bonded CF3 group is found to be a simple, unprecedented route to a new borane carbonyl. The related, thermally unstable borane carbonyl, (C6F5)(3)BCO, is synthesized for comparison purposes by the isolation of (C6F5)(3)B in a matrix of solid CO at 16 K and subsequent evaporation of excess CO at 40 K. The colorless liquid and vapor of (CF3)3BCO decomposes slowly at room temperature. In the gas phase t(1/2) is found to be 45 min. In the presence of a large excess of (CO)-C-13, the carbonyl substituent at boron undergoes exchange, which follows a first-order rate law. Its temperature dependence yields an activation energy (EA) of 112 kJ mol(-1). Low-pressure flash thermolysis of (CF3)3BCO with subsequent isolation of the products in low-temperature matrixes, indicates a lower thermal stability of the (CF3)3B fragment, than is found for (CF3)3BCO. Toward nucleophiles (CF3)3BCO reacts in two different ways: Depending on the nucleophilicity of the reagent and the stability of the adducts formed, nucleophilic substitution of CO or nucleophilic addition to the C atom of the carbonyl group are observed. A number of examples for both reaction types are presented in an overview. The molecular structure of (CF3)(3)BCO in the gas phase is obtained by a combined microwave-electron diffraction analysis and in the solid state by single-crystal X-ray diffraction. The molecule possesses C3 symmetry, since the three CF3 groups are rotated off the two possible positions required for C3, symmetry. All bond parameters, determined in the gas phase or in the solid state, are within their standard deviations in fair agreement, except for internuclear distances most noticeably the B-CO bond lengths, which is 1.69(2) Angstrom in the solid state and 1.617(12) Angstrom in the gas phase. A corresponding shift of nu(CO) from 2267 cm(-1) in the solid state to 2251 cm-1 in the gas phase is noted in the vibrational spectra. The structural and vibrational study is supported by DFT calculations, which provide, in addition to the equilibrium structure, confirmation of experimental vibrational wavenumbers, IR-band intensities, atomic charge distribution, the dipole moment, the B-CO bond energy, and energies for the elimination of CF2 from (CF3)(x)BF3-x1 = 1-3. In the vibrational analysis 21 of the expected 26 fundamentals are observed experimentally. The B-11-, C-13-, and F-19-NMR data, as well as the structural parameters of (CF3)(3)BCO, are compared with those of related compounds.},

The thermally unstable methylidene complex decomposes in solution in the absence of trapping agents to unidentified products. However, in the presence of ethylene [P2N2]Ta=CH2(Me) is slowly converted to [P2N2]Ta(C2H4)Et, with [P2N2]Ta(C2H4)Me observed as a minor product. A mechanistic study suggests that the formation of [P2N2]Ta(C2H4)Et results from the trapping of [P2N2]TaEt, formed by the migratory insertion of the methylene moiety into the tantalum-methyl bond. The minor product, [P2N2]Ta(C2H4)Me, forms from the decomposition of a tantalacyclobutane resulting from the addition of ethylene to [P2N2]Ta=CH2(Me) and is accompanied by the production of an equivalent of propylene. Pure [P2N2]Ta(C2H4)Et can be synthesized by hydrogenation of [P2N2]TaMe3 in the presence of PMe3, followed by the reaction bf ethylene with the resulting trihydride. Crystallographic and NMR data indicate the presence of a beta -agostic interaction between the ethyl group and tantalum center in [P2N2]Ta(C2H4)Et. Partially deuterated analogues of [P2N2]Ta(C2H4)Et show a large isotopic perturbation of resonance for both the beta -protons and the alpha -protons of the ethyl group, indicative of an equilibrium between a beta -agostic and an a-agostic interaction for the ethyl group in solution. An EXSY spectrum demonstrates that an additional fluxional process occurs that exchanges all of the H-1 environments of the ethyl and ethylene ligands. The mechanism of this exchange is believed to involve the direct transfer of the beta -agostic hydrogen atom from the ethyl group to the ethylene ligand, via the so-called beta -hydrogen transfer process.},

Under 4 atm of hydrogen gas, further hydrogenation does not produce the complex [P2N2]TaH3; instead, reduction of the tantalum center occurs to yield the dinuclear Ta(IV) hydride ([P2N2]Ta)(2)-(mu-H)(4). This diamagnetic tetrahydride fails to react with many reagents, including ethylene and carbon monoxide; however, upon addition of iodomethane, {([P2N2]Ta)(2)(mu-H)(4)}I-+(-) is produced as a paramagnetic green crystalline solid. The number of hydrides in this reaction product was confirmed by a deuterium labeling study. The results of a variable-temperature magnetic susceptibility study of this tetrahydride cation can be partially modeled with the Curie-Weiss law and a large correction for temperature-independent magnetism. Ab initio calculations using density functional theory were performed in an attempt to further understand the influence of the macrocyclic ligand in the bonding in these complexes.},

The magnetic properties were analyzed employing a model for S = 1 which takes into account zero-field splitting and employs a molecular field term to account for weak magnetic exchange. The compounds Ni(pyz)Cl-2 and Ni(py)Cl-2, show metamagnetic behaviour with critical fields of 13 and 2 kOe, respectively, at 2 K. In these compounds nickel ions, linked in chains by bridging chlorides, exhibit intrachain ferromagnetic and interchain antiferromagnetic exchange. In Ni(pyz)Cl-2, bridging pyrazine ligands are considered to provide the pathway for the antiferromagnetic coupling resulting in a high critical field.},

Metalation of the substituted aromatic ring results in one complex, Os-3(CO)(9)(mu-H)[(C10H7)(2)P-(C10H6)]. Cleavage of an As-naphthyl bond affords a low yield of the naphthyne complex Ru-4(CO)(10)(mu-CO)[mu(4)-As(C10H7)][mu(4)-C10H6] (11), in which the aryne ring is at an angle of 75 degrees to the RU(4) plane and acts as a four-electron donor, making 11 formally electron deficient.
