In3Ir crystallizes in the tetragonal P4_2/mnm space group. Ir(1) is bonded in a 8-coordinate geometry to two 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 linear geometry to two equivalent Ir(1) atoms.
In3Ir crystallizes in the tetragonal P4_2/mnm space group. Ir(1) is bonded in a 8-coordinate geometry to two equivalent In(2) and six equivalent In(1) atoms. Both Ir(1)-In(2) bond lengths are 2.66 Å. There are two shorter (2.68 Å) and four longer (2.80 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 linear geometry to two equivalent Ir(1) atoms.
