Ta Sn Ir Ir
TaIr2Sn crystallizes in the triclinic P1 space group. Ta(1) is bonded in a 7-coordinate geometry to four equivalent Ta(1), one Ir(2), and two equivalent Sn(1) atoms. There are two shorter (3.02 Å) and two longer (3.39 Å) Ta(1)-Ta(1) bond lengths. The Ta(1)-Ir(2) bond length is 3.75 Å. There is one shorter (3.47 Å) and one longer (3.74 Å) Ta(1)-Sn(1) bond length. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a distorted L-shaped geometry to one Ir(2) and one Sn(1) atom. The Ir(1)-Ir(2) bond length is 0.43 Å. The Ir(1)-Sn(1) bond length is 1.04 Å. In the second Ir site, Ir(2) is bonded in a distorted single-bond geometry to one Ta(1) and one Ir(1) atom. Sn(1) is bonded in a distorted single-bond geometry to two equivalent Ta(1) and one Ir(1) atom.
