Nickel(II)–bismuth(III) bond formation in nickel(II) complexes of tris(o-dimethylarsinophenyl)bismuthine
Abstract
Tris(o-dimethylarsinophenyl)bismuthine (bitas) forms the square pyramidal complexes [Ni(bitas)X]BPh4(X = halide), the first examples of trivalent bismuth co-ordinated to a 3d transition metal in a positive oxidation state, and [Ni2(bitas)3]4+, which contains examples of bitas functioning as a tridentate and a tetra-dentate ligand.
