Tl Cd Tc Ni
TcNiCdTl crystallizes in the trigonal R3m space group. Tc(1) is bonded in a 10-coordinate geometry to four equivalent Ni(1), three equivalent Cd(1), and three equivalent Tl(1) atoms. There are three shorter (2.81 Å) and one longer (2.83 Å) Tc(1)-Ni(1) bond length. All Tc(1)-Cd(1) bond lengths are 2.69 Å. All Tc(1)-Tl(1) bond lengths are 2.69 Å. Ni(1) is bonded in a single-bond geometry to four equivalent Tc(1), three equivalent Cd(1), and one Tl(1) atom. All Ni(1)-Cd(1) bond lengths are 2.69 Å. The Ni(1)-Tl(1) bond length is 1.39 Å. Cd(1) is bonded in a 10-coordinate geometry to three equivalent Tc(1), three equivalent Ni(1), and four equivalent Tl(1) atoms. There are three shorter (2.81 Å) and one longer (2.83 Å) Cd(1)-Tl(1) bond length. Tl(1) is bonded in a single-bond geometry to three equivalent Tc(1), one Ni(1), and four equivalent Cd(1) atoms.
