Cr2ZnO5 crystallizes in the orthorhombic Cmcm space group. Cr(1) is bonded to one O(1), one O(3), and three equivalent O(2) atoms to form a mixture of distorted edge and corner-sharing CrO5 trigonal bipyramids. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Cr(1) and two equivalent Zn(1) atoms to form corner-sharing OZn2Cr2 tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent Cr(1) and one Zn(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Cr(1) and one Zn(1) atom.

Cr(1) is bonded to one O(1), one O(3), and three equivalent O(2) atoms to form a mixture of distorted edge and corner-sharing CrO5 trigonal bipyramids. The Cr(1)-O(1) bond length is 1.98 Å. The Cr(1)-O(3) bond length is 1.71 Å. There are two shorter (1.94 Å) and one longer (1.98 Å) Cr(1)-O(2) bond length. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Both Zn(1)-O(1) bond lengths are 2.11 Å. Both Zn(1)-O(2) bond lengths are 2.43 Å. Both Zn(1)-O(3) bond lengths are 1.97 Å. There are three inequivalent O sites.
