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.},
