Cr Cd As As
CdCr(As)2 is alpha carbon monoxide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two diarsene molecules and two CdCr clusters. In each CdCr cluster, Cr(1) is bonded in a single-bond geometry to one Cd(1) atom. The Cr(1)-Cd(1) bond length is 0.27 Å. Cd(1) is bonded in a single-bond geometry to one Cr(1) atom.
