The material described by ZnCrO4 crystallizes in the monoclinic P2_1/c space group. Cr(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form CrO4 tetrahedra that share corners with four equivalent Zn(1)O4 trigonal pyramids. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form distorted ZnO4 trigonal pyramids that share corners with four equivalent Cr(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Cr(1) and one Zn(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Cr(1) and one Zn(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Cr(1) and one Zn(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Cr(1) and one Zn(1) atom. is represented by the CIF file [CIF]
