Ta Cd Cd Cd Cd Tc
TaTcCd4 crystallizes in the trigonal R3m space group. Ta(1) is bonded in a 6-coordinate geometry to three equivalent Tc(1) and three equivalent Cd(1) atoms. All Ta(1)-Tc(1) bond lengths are 3.42 Å. All Ta(1)-Cd(1) bond lengths are 0.89 Å. Tc(1) is bonded in a distorted single-bond geometry to three equivalent Ta(1) and one Cd(2) atom. The Tc(1)-Cd(2) bond length is 1.55 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 2-coordinate geometry to one Ta(1), one Cd(2), and two equivalent Cd(1) atoms. The Cd(1)-Cd(2) bond length is 0.72 Å. Both Cd(1)-Cd(1) bond lengths are 0.42 Å. In the second Cd site, Cd(2) is bonded in a distorted single-bond geometry to one Tc(1) and three equivalent Cd(1) atoms.
