Ir2Ge3Se3 is Skutterudite-derived structured and crystallizes in the cubic Pm-3 space group. Ir(1) is bonded to three equivalent Ge(1) and three equivalent Se(1) atoms to form corner-sharing IrGe3Se3 octahedra. The corner-sharing octahedral tilt angles range from 56-57°. Ge(1) is bonded in a 4-coordinate geometry to two equivalent Ir(1) and two equivalent Ge(1) atoms. Se(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Ir(1) and two equivalent Se(1) atoms.
Ir2Ge3Se3 is Skutterudite-derived structured and crystallizes in the cubic Pm-3 space group. Ir(1) is bonded to three equivalent Ge(1) and three equivalent Se(1) atoms to form corner-sharing IrGe3Se3 octahedra. The corner-sharing octahedral tilt angles range from 56-57°. All Ir(1)-Ge(1) bond lengths are 2.53 Å. All Ir(1)-Se(1) bond lengths are 2.45 Å. Ge(1) is bonded in a 4-coordinate geometry to two equivalent Ir(1) and two equivalent Ge(1) atoms. There is one shorter (2.47 Å) and one longer (2.99 Å) Ge(1)-Ge(1) bond length. Se(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Ir(1) and two equivalent Se(1) atoms. There is one shorter (2.61 Å) and one longer (2.82 Å) Se(1)-Se(1) bond length.
