Ta Tl Tc Ir
TaTcIrTl crystallizes in the trigonal R3m space group. Ta(1) is bonded in a 10-coordinate geometry to three equivalent Tc(1), three equivalent Ir(1), and four equivalent Tl(1) atoms. All Ta(1)-Tc(1) bond lengths are 2.70 Å. All Ta(1)-Ir(1) bond lengths are 2.70 Å. There is one shorter (2.73 Å) and three longer (2.84 Å) Ta(1)-Tl(1) bond lengths. Tc(1) is bonded in a single-bond geometry to three equivalent Ta(1), four equivalent Ir(1), and one Tl(1) atom. There is one shorter (2.73 Å) and three longer (2.84 Å) Tc(1)-Ir(1) bond lengths. The Tc(1)-Tl(1) bond length is 1.52 Å. Ir(1) is bonded in a 10-coordinate geometry to three equivalent Ta(1), four equivalent Tc(1), and three equivalent Tl(1) atoms. All Ir(1)-Tl(1) bond lengths are 2.70 Å. Tl(1) is bonded in a single-bond geometry to four equivalent Ta(1), one Tc(1), and three equivalent Ir(1) atoms.
