Cr2ZnO6 crystallizes in the orthorhombic Pmn2_1 space group. Cr(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles range from 28-48°. Zn(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one Zn(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Cr(1) and one Zn(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Cr(1) and one Zn(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to two equivalent Cr(1) atoms.
