1,12-Digermacyclodocosanes. Synthesis, structure and anion transport capability

Abstract

An X-ray crystallographic analysis indicated that 1,1,12,12-tetramethyl-1,12-digermacyclodocosane exists exclusively as the [3838] conformer with germanium atoms at corner sites in the crystalline state. The geometric parameters of this compound are nicely reproduced by MM3 calculations and are found to be comparable with those of relevant carbocycles. The anion transport capability of 1,12-dichloro-1,12-dimethyl-1,12-digermacyclodocosane is much the same with that of the 14-membered-ring analogue.
