Cd Cu Sn Te
CuCdSnTe crystallizes in the trigonal R3m space group. Cu(1) is bonded to one Cd(1) and three equivalent Te(1) atoms to form distorted CuCdTe3 trigonal pyramids that share  a cornercorner with one Te(1)CdCu3Sn trigonal bipyramid, corners with three equivalent Cd(1)CuSn3Te trigonal bipyramids, corners with six equivalent Cu(1)CdTe3 trigonal pyramids, and edges with three equivalent Sn(1)Cd3Te trigonal pyramids. The Cu(1)-Cd(1) bond length is 2.18 Å. All Cu(1)-Te(1) bond lengths are 2.99 Å. Cd(1) is bonded to one Cu(1), three equivalent Sn(1), and one Te(1) atom to form distorted CdCuSn3Te trigonal bipyramids that share corners with six equivalent Cd(1)CuSn3Te trigonal bipyramids,  a cornercorner with one Sn(1)Cd3Te trigonal pyramid, corners with three equivalent Cu(1)CdTe3 trigonal pyramids, and edges with three equivalent Te(1)CdCu3Sn trigonal bipyramids. All Cd(1)-Sn(1) bond lengths are 2.99 Å. The Cd(1)-Te(1) bond length is 2.18 Å. Sn(1) is bonded to three equivalent Cd(1) and one Te(1) atom to form distorted SnCd3Te trigonal pyramids that share  a cornercorner with one Cd(1)CuSn3Te trigonal bipyramid, corners with three equivalent Te(1)CdCu3Sn trigonal bipyramids, corners with six equivalent Sn(1)Cd3Te trigonal pyramids, and edges with three equivalent Cu(1)CdTe3 trigonal pyramids. The Sn(1)-Te(1) bond length is 2.18 Å. Te(1) is bonded to three equivalent Cu(1), one Cd(1), and one Sn(1) atom to form distorted TeCdCu3Sn trigonal bipyramids that share corners with six equivalent Te(1)CdCu3Sn trigonal bipyramids,  a cornercorner with one Cu(1)CdTe3 trigonal pyramid, corners with three equivalent Sn(1)Cd3Te trigonal pyramids, and edges with three equivalent Cd(1)CuSn3Te trigonal bipyramids.
