	abstract = {Platinum(II) and palladium(II) complexes of the potentially hexadentate P,N-donor ligand family Ar2P-X-PAr2 (X = (CH2)(2) [dmape], cyclic-C5H8 [dmapcp]; Ar = o-NN-dimethylanilinyl) are described. In CH2Cl2, the dmape complexes exist as equilibrium mixtures of MCl2(P,P{\textquoteright}-dmape) and [MCl(P, P, N-dmape)]Cl isomers (M = Pd, Pt), governed by Delta H degrees = -19 +/- 4 U mol(-1) and Delta S degrees = -100 +/- 30 J mol(-1) K-1 for M = Pt, and Delta H degrees = -11 +/- 7 U mol-1 and Delta S degrees = -60 +/- 20 J mol-1 K-1 for M = Pd. The water-soluble dmapcp complexes exist solely in the [MCl(P,P{\textquoteright},N-dmapcp)]Cl form, but the free and coordinated anilinyl rings in these complexes are in slow diastereoselective exchange, X-ray crystal structures for MCl2(P,P{\textquoteright}-dmape) (M = Pd, Pt), and the [PdCl(P,P{\textquoteright},N-dmape)](+) and [PtCl-P,P{\textquoteright},N-dmapcp)](+) cations, are presented. Some of the complexes show marginal activity in water for the catalyzed hydration of maleic to malic acid, giving about 6-7\% conversion in 24 h at 100 degrees C and substrate: catalyst loadings of 100:1. Attempts to synthesize a PdCl(P,P{\textquoteright},N-dmapm)(+) species led instead to isolation of [Pd(mu-Cl)(P,P-dmapm)](2)-[PF6](2) (dmapm = Ar2PCH2Ar2).},

Several short, intramolecular C-H...N distances in the anilinyl derivatives may represent the presence of weak hydrogen bonds.},

	abstract = {{Complexes incorporating the [Re=O](3+) core have been synthesised with ligands containing the new methyl substituted phosphine-phenolate PO and PO2 donor sets, (2-hydroxy-5-methylphenyl) diphenylphosphine (H(MePO)) and bis(2-hydroxy-5-methylphenyl) phenylphosphine (H-2(Me2PO2)). The analogous tert-butyl ligands, (5-tert-butyl-2-hydroxyphenyl)diphenylphosphine (H(t-BuPO)) and bis(5-tert-butyl-2-hydroxyphenyl) phenylphosphine (H-2 (t-Bu2PO2)), were also prepared. Reaction of either mer-[ReOCl3 (PPh3)(2)] or [NH4][ReO4] in CH3OH with H(MePO) led to formation of [ReOCl(MePO)(2)] (1) in good yield. Reaction of [NH4][ReO4] with H-2 (Me2PO2) in CH3OH afforded [ReO(Me2PO2)(H(Me2PO2))] (2), also in good yield. X-Ray crystallographic analyses of 1 and 2 demonstrated that both complexes are neutral and octahedral, and contain the oxo moiety. Two complexes have been structurally characterised from the reaction of (o-hydroxyphenyl) diphenylphosphine (HPO) with [Re(Hhypy)(hypyH)Cl-3]: [Re(Hhypy)(hypy)(PO)(HPO)]Cl (3) and [ReCl(Hypy)(hypy)(PO)] (4) (hypy = NNC5H4N},
