IrZn2SnO6 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 Sn(1)O6 octahedra and corners with eight equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. 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 Sn(1)O6 octahedra, and corners with two equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 63-83°. Sn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SnO6 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 are 46°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Ir(1), two equivalent Zn(1), and one Sn(1) atom to form distorted corner-sharing OZn2SnIr tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Ir(1), one Zn(1), and one Sn(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Ir(1), one Zn(1), and one Sn(1) atom.
