IrCoZn2O6 crystallizes in the monoclinic P2_1/c space group. 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 Co(1)O6 octahedra and corners with eight equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 42-43°. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with six equivalent Ir(1)O6 octahedra and corners with eight equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 42-43°. Zn(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form distorted ZnO4 tetrahedra that share corners with four equivalent Ir(1)O6 octahedra, corners with four equivalent Co(1)O6 octahedra, and corners with two equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 65-83°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Ir(1), one Co(1), and two equivalent Zn(1) atoms to form distorted corner-sharing OZn2CoIr tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ir(1), one Co(1), and one Zn(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Ir(1), one Co(1), and one Zn(1) atom.
