Abstrakt: The use of pyridine-2-amidoxime in reaction with NiCl2.6H2O in the presence of NaOMe has led to a cationic NiII 12 cluster with novel structural features; each cluster molecule is a ferromagnet with a spin ground state of S = 6 arising from ferromagnetic exchange between the six octahedral NiII ions, but with intercationic interactions also affecting the magnetic properties.
