Sn Ge Ir Ir
Ir2SnGe crystallizes in the triclinic P1 space group. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a single-bond geometry to two equivalent Sn(1) and one Ge(1) atom. There is one shorter (2.90 Å) and one longer (3.29 Å) Ir(1)-Sn(1) bond length. The Ir(1)-Ge(1) bond length is 0.97 Å. In the second Ir site, Ir(2) is bonded in a single-bond geometry to two equivalent Sn(1) and one Ge(1) atom. There is one shorter (2.90 Å) and one longer (3.18 Å) Ir(2)-Sn(1) bond length. The Ir(2)-Ge(1) bond length is 1.19 Å. Sn(1) is bonded in a 7-coordinate geometry to two equivalent Ir(1), two equivalent Ir(2), two equivalent Sn(1), and one Ge(1) atom. Both Sn(1)-Sn(1) bond lengths are 3.09 Å. The Sn(1)-Ge(1) bond length is 2.52 Å. Ge(1) is bonded in a distorted bent 120 degrees geometry to one Ir(1), one Ir(2), and one Sn(1) atom.
