The X-ray analysis revealed two 3D interpenetrating alpha -polonium networks consisting of 1D chains of Cu-pyrazine units connected by [Au(CN)(2)] bridges. The two networks are connected via weak aurophilic interactions (Au-Au: 3.4729(2) Angstrom). Thermogravimetric analysis of all three compounds indicated the robust nature of these 3D systems, with decomposition beginning at 260 (1), 406 (2) and 360 degreesC (3).

A comparison of the magnetic properties of the polymeric diazine-bridged complexes, Ni(pyz)(2)X(2) (X = Cl or NO3), Ni(pyz)(p-CH3C6H4SO3)(2), Ni(mepyz)(NO3)(2), and Ni(pyz)(3)(CH3SO3)(2).CH3OH with those of the related monometallic systems, Ni(py)(4)X(2) (X = Cl, p-CH3C6H4SO3 or CH3SO3) and Ni(mepyz)(4)(NO3)(2).H2O provides evidence for weak antiferromagnetic coupling between metal centers mediated by bridging diazine ligands in the former group of compounds. 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.},

	abstract = {Muon resonance studies show that muonium atoms (Mu) in ethanol add selectively to certain C-sites of aromatic compounds containing -Cl and -OH substituents. The sites chosen seem to be those carrying the lowest electron density. This helps to characterize Mu as a nucleophile in addition reactions and, in this respect, Mu differs from ordinary H-atoms. The study shows no apparent inter-molecular selectivity between a pair of aromatic solutes in an equimolar mixture, but strong intra-molecular selectivity in an ether composed of those two aromatic rings. This difference between intra- and inter-molecular selectivity is interpreted as kinetic in origin - arising from the {\textquoteright}caging effect{\textquoteright} of the solvent and peculiar to reactions close to the diffusion-controlled limit.},
