In3Ir is Cementite structured and crystallizes in the orthorhombic Pnma space group. Ir(1) is bonded in a 9-coordinate geometry to three equivalent In(2) and six equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. In the second In site, In(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms.
In3Ir is Cementite structured and crystallizes in the orthorhombic Pnma space group. Ir(1) is bonded in a 9-coordinate geometry to three equivalent In(2) and six equivalent In(1) atoms. There are a spread of Ir(1)-In(2) bond distances ranging from 2.77-2.96 Å. There are four shorter (2.77 Å) and two longer (2.79 Å) Ir(1)-In(1) bond lengths. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. In the second In site, In(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms.
