Ge Ge Ge Ge Ir Pt
IrPtGe4 crystallizes in the trigonal R3m space group. Ir(1) is bonded in a distorted single-bond geometry to one Pt(1) and three equivalent Ge(1) atoms. The Ir(1)-Pt(1) bond length is 1.74 Å. All Ir(1)-Ge(1) bond lengths are 2.87 Å. Pt(1) is bonded in a distorted rectangular see-saw-like geometry to one Ir(1) and three equivalent Ge(1) atoms. All Pt(1)-Ge(1) bond lengths are 1.51 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 5-coordinate geometry to one Ir(1), one Pt(1), one Ge(2), and two equivalent Ge(1) atoms. The Ge(1)-Ge(2) bond length is 1.20 Å. Both Ge(1)-Ge(1) bond lengths are 0.69 Å. In the second Ge site, Ge(2) is bonded in a 3-coordinate geometry to three equivalent Ge(1) atoms.
