Cd Cd Te Au
AuCd2Te crystallizes in the monoclinic Cm space group. Au(1) is bonded in a 5-coordinate geometry to four equivalent Cd(1) and one Te(1) atom. There are two shorter (2.63 Å) and two longer (3.31 Å) Au(1)-Cd(1) bond lengths. The Au(1)-Te(1) bond length is 2.69 Å. Cd(1) is bonded in a single-bond geometry to two equivalent Au(1) and one Te(1) atom. The Cd(1)-Te(1) bond length is 1.18 Å. Te(1) is bonded in a distorted L-shaped geometry to one Au(1) and two equivalent Cd(1) atoms.
