BaIrIn4 crystallizes in the orthorhombic Pmma space group. Ba(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 Ba(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 4-coordinate geometry to two equivalent Ba(1), two equivalent Ir(1), and four equivalent In(2) atoms. In the second In site, In(2) is bonded in a 12-coordinate geometry to four equivalent Ba(1), two equivalent Ir(1), two equivalent In(1), two equivalent In(2), and two equivalent In(3) atoms. In the third In site, In(3) is bonded in a linear geometry to two equivalent Ba(1), two equivalent Ir(1), and four equivalent In(2) atoms.
