Ta Cd Cd W
TaWCd2 crystallizes in the trigonal R3m space group. Ta(1) is bonded in a single-bond geometry to four equivalent W(1) and one Cd(1) atom. There are three shorter (2.72 Å) and one longer (3.72 Å) Ta(1)-W(1) bond length. The Ta(1)-Cd(1) bond length is 0.18 Å. W(1) is bonded in a 10-coordinate geometry to four equivalent Ta(1), three equivalent Cd(1), and three equivalent Cd(2) atoms. All W(1)-Cd(1) bond lengths are 2.71 Å. All W(1)-Cd(2) bond lengths are 2.71 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a single-bond geometry to one Ta(1) and three equivalent W(1) atoms. In the second Cd site, Cd(2) is bonded in a distorted trigonal planar geometry to three equivalent W(1) atoms.
