Abstract

An X-ray structural study of the iodide and triiodide of bis-(2-oxo-1-hexahydroazepinylmethyl) chlorogermane (1 and2, respectively;R=0.033 and 0.031 on 3276 and 3093 reflections, respectively) attests to the essentially ionic structure of both compounds with weak I→Ge coordination: the I...Ge distances are 4.181(1)–4.219(2)Å, the Cl-Ge...I angles are 171.6(1)-180°, the coordination polyhedron of the Ge atom is a distorted trigonal bipyramid (without regard for the iodide ligands). A comparison of structures1 and2, and other derivatives of penta- and hexacoordinated Ge shows that in certain cases, the electronic system of this atom with its coordination environment may be considered as containing a combination of two weakly interacting hypervalent X-Ge-X' moieties.
