Crystal structure of arsenic trichloride–trimethylamine, AsCl3,NMe3

Abstract

The title compound has been examined by single-crystal X-ray diffraction and crystallises in the space group P21/c with Z= 4 in a unit cell of dimensions a= 6·14, b= 10·33, c= 14·85 A, and β= 107·0°. The structure consists of discrete AsCl3,NMe3 molecules which may be considered to be based on trigonal bipyramidal arsenic co-ordination and the photographically estimated three-dimensional data were refined to R 0·083.
