(2-Carbamoylethyl-κC,O)triiodidotin(IV)

Abstract

Two independent but virtually identical mol-ecules comprise the asymmetric unit of the title compound, [Sn(C(3)H(6)NO)I(3)]. The CI(3)O coordination geometry around the Sn(IV) atom is defined by a chelating carbamoylethyl ligand (C(1),O-bidentate) and three I atoms, and is based on a distorted trigonal bipyramid with the carbonyl O atom occupying a position trans to one of the I atoms which forms the longer of the Sn-I bonds. The independent mol-ecules are linked via N-H⋯O hydrogen bonds, which leads to the formation on an eight-membered amide {⋯HNCO}(2) synthon. N-H⋯I hydrogen-bonding inter-actions are also present between neighbouring mol-ecules.
