Abstract
The trisubstituted stibine, tris(o-dimethylarsinophenyl)stibine, sbtas, forms complexes of type [Pd(sbtas)X]Y (X = Cl, Br, I, SCN; Y = Cl, CNS, BPh4) which are five-co-ordinate and trigonal bipyramidal. The electronic spectra of these complexes show a shift of the ligand-field bands to higher energy in the order I– > Br– > Cl–, and this nephelauxetic behaviour is discussed in relation to the compression of the Pd–Sb linkage as a result of chelation.Keywords
