Аннотация:Anionic Sb(V) complexes, namely, PyH[PbSbCl5] (I), PyH[PhSbBr5] (II), and QH[PhSbCl5] (III), were synthesized and subjected to x-ray diffraction structural analysis. In going from the [SbX6] octahedron (X = Cl and Br) with an equivalent environment of the Sb atom to the [PhSbX5] octahedron, there is an increase in the length of the Sb-X bonds only in the cis position relative to the phenyl ligand. In contrast to octahedral Sn(IV) and Pb(IV) complexes, there is no trans effect of the phenyl group in I-III.
