Tc2Cd is alpha Po structured and crystallizes in the trigonal R3 space group. The structure is zero-dimensional and consists of three Tc2Cd clusters. There are four inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 5-coordinate geometry to one Tc(4), two equivalent Tc(1), and two equivalent Tc(2) atoms. The Tc(1)-Tc(4) bond length is 1.11 Å. Both Tc(1)-Tc(1) bond lengths are 1.14 Å. Both Tc(1)-Tc(2) bond lengths are 1.11 Å. In the second Tc site, Tc(2) is bonded in a 5-coordinate geometry to one Tc(3), two equivalent Tc(1), and two equivalent Tc(2) atoms. The Tc(2)-Tc(3) bond length is 1.11 Å. Both Tc(2)-Tc(2) bond lengths are 1.14 Å. In the third Tc site, Tc(3) is bonded in a 3-coordinate geometry to three equivalent Tc(2) atoms. In the fourth Tc site, Tc(4) is bonded in a 4-coordinate geometry to three equivalent Tc(1) and one Cd(1) atom. The Tc(4)-Cd(1) bond length is 2.54 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to one Tc(4) and three equivalent Cd(2) atoms. All Cd(1)-Cd(2) bond lengths are 1.27 Å. In the second Cd site, Cd(2) is bonded in a 3-coordinate geometry to one Cd(1) and two equivalent Cd(2) atoms. Both Cd(2)-Cd(2) bond lengths are 1.27 Å.
