Abstract
Interaction of ortho-phenylenediamine with the nonanuclear nickel trimethylacetate cluster Ni9(μ4-OH)3(μ3-OH)3(μ n -OOCMe3)12(HOOCCMe3)4(I) in an amine deficiency yields the antiferromagnetic trinuclear complex [Ni3{μ-N,N"-(NH2)2C6H4}2(HCCOOCMe3)3(μ3-OH)(μ-OOCCMe3)4]+(OOCCMe3)–(III) containing bridging diamine ligands. Reaction of excess diamine with Ior IIIleads to the formation of the paramagnetic monomer Ni{η2-o-(NH2)2C6H4}2(OOCCMe3)2(IV), which reacts with atmospheric oxygen to form the known bis(semiquinonediimine) complex Ni[1,2-(NH)2C6H4]2(V).
