Popis: The trisubstituted stibine, tris(o-dimethylarsinophenyl)stibine (sbta) reacts with nickel(II) salts to form complexes of type [Ni(sbta)X]Y (X = Cl, Br, I, NCS, and NO3; Y = Cl, Br, I, CNS, NO3, and BPh4) and [Ni(sbta)2]Z2(Z = ClO4 and BPh4). These diamagnetic complexes are five-co-ordinate, the [Ni(sbta)X]+ species being trigonal bipyramidal while the [Ni(sbta)2]2+ species are square pyramidal. The visible spectra of these complexes are discussed and compared with those of other complexes containing ligands with the SbAS3 and As4 donor sets.
