Cd Sb Sb Sb Sb As
CdSb4As crystallizes in the trigonal R3m space group. Cd(1) is bonded in a 4-coordinate geometry to three equivalent Sb(1) and one As(1) atom. All Cd(1)-Sb(1) bond lengths are 2.55 Å. The Cd(1)-As(1) bond length is 2.94 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 5-coordinate geometry to one Cd(1), one Sb(2), two equivalent Sb(1), and one As(1) atom. The Sb(1)-Sb(2) bond length is 2.09 Å. Both Sb(1)-Sb(1) bond lengths are 1.21 Å. The Sb(1)-As(1) bond length is 2.90 Å. In the second Sb site, Sb(2) is bonded in a 3-coordinate geometry to three equivalent Sb(1) atoms. As(1) is bonded in a trigonal pyramidal geometry to one Cd(1) and three equivalent Sb(1) atoms.
