The compound described by CrWO4 is Hydrophilite-derived structured and crystallizes in the monoclinic Cm space group. W(1) is bonded to two O(1,1); two O(2,2); and two O(3,3) atoms to form WO6 octahedra that share corners with eight Cr(1,1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-52°. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(1); one O(2); and four O(3,3) atoms to form CrO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-52°. In the second Cr site, Cr(1) is bonded to one O(1); one O(2); and four O(3,3) atoms to form CrO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-52°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent W(1) and one Cr(1) atom. In the second O site, O(1) is bonded in a trigonal planar geometry to two equivalent W(1) and one Cr(1) atom. In the third O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent W(1) and one Cr(1) atom. In the fourth O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent W(1) and one Cr(1) atom. In the fifth O site, O(3) is bonded in a distorted trigonal planar geometry to one W(1) and two Cr(1,1) atoms. In the sixth O site, O(3) is bonded in a distorted trigonal planar geometry to one W(1) and two Cr(1,1) atoms. is represented by the CIF file [CIF]
