CaIrIn4 crystallizes in the orthorhombic Pmma space group. Ca(1) is bonded in a 13-coordinate geometry to one Ir(1), two equivalent In(1), two equivalent In(3), and eight equivalent In(2) atoms. Ir(1) is bonded in a 9-coordinate geometry to one Ca(1), two equivalent In(1), two equivalent In(3), and four equivalent In(2) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a linear geometry to two equivalent Ca(1) and two equivalent Ir(1) atoms. In the second In site, In(2) is bonded in a 2-coordinate geometry to four equivalent Ca(1) and two equivalent Ir(1) atoms. In the third In site, In(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ca(1) and two equivalent Ir(1) atoms.
