Die Kristallstrukturen von Tetramethylarsonium- und Tetramethylstibonium-monomethyltrichloroindat (CH3)4M+CH3InCl3 - (mit M = As, Sb).

Abstract

Tetramethylarsonium-, as well as tetramethylstibonium-monomethyltrichloroindate crystallizes in the monoclinic space-group Pc with two formula units in the cell. In both structures we found isolated (CH3)4M+- and (CH3)InCl3 -- tetrahedra (M = As, Sb), from which the anionic one in markedly distorted. The distances between these isolated tetrahedral cations and anions are not equal. The tetrahedrical cations and anions form double-layers.
