Using pyridine amidoximes in 3d-metal cluster chemistry: a novel ferromagnetic Ni(12) complex from the use of pyridine-2-amidoxime.

The use of pyridine-2-amidoxime in reaction with NiCl(2) center dot 6H(2)O in the presence of NaOMe has led to a cationic Ni(12)(II) 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 Ni(II) ions, but with intercationic interactions also affecting the magnetic properties.
