Structures and magnetic properties of di and tetranuclear nickel(II) complexes with Schiff base ligands
Reactions of Ni(CH3COO)(2).4H(2)O and NiCl2.6H(2)O with Schiff base ligands yielded di and tetranuclear nickel(II) complexes of [Ni-2(Hhsae)(2)(CH3COO)(2)(MeOH)(2)] (1) and [Ni-4(sae)(4)(MeOH)(4)] (2) (H(2)hsae = 2-(5-hydroxysalicylideneamino)ethanol and H(2)sae = 2-salicylideneaminoethanol). Magnetic susceptibility measurements revealed that 1 and 2 have singlet and nonet spin ground states, respectively.
