Abstract

The anion [N(SePPh2)(2)](-) forms stable complexes with cations M(II, III); [M(II) = Sn, Se, Cd, Hg; M(III) = In, Sb, Bi], they exhibit a large diversity of structural arrangements around the metal centre. Tin(II) complex crystallizes dimorphically, as square planar and distorted tetragonal pyramidal, Pb(II) is also distorted tetragonal pyramidal, Cd(II) and Hg(II) are tetrahedral, but the Se(II) is square planar. The coordination geometry in the M(III) complexes can be described as a distorted octahedron. The structural situation around the Sb(III) and Bi(III) suggests a stereochemically non-active electron lone pair.
