The compound described by CrIrO6 crystallizes in the monoclinic P2_1/c space group. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CrO6 octahedra that share corners with six equivalent Ir(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-35°. Ir(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form IrO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-35°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Cr(1) and one Ir(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Cr(1) and one Ir(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Cr(1) and one Ir(1) atom. is represented by the CIF card [CIF]
