Abstract
The title molecule, [ASCl(2)(C6H11)(3)], has a distorted trigonal-bipy ramidal geometry with three equatorial cyclohexyl groups and axial Cl atoms. The As-C distances [1.990(2), 1.988(2) and 1.981(3) Angstrom] d iffer slightly, and the equatorial angles C-As-C are 117.35(10), 117.6 0(10) and 123.26(8)degrees. The angle subtended at arsenic by the axia l Cl atoms is 178.60(2)degrees, but the chlorine separation distances [2.4957(7) and 2.3029(7) Angstrom] differ substantially. The As atom l ies out of the plane of the equatorial C atoms, suggesting a contribut ion from the ionic structure, [As(cyclo-C6H11)(3)Cl]Cl-+(-).
