The compound described by YCr(WO4)2 is Hydrophilite-derived structured and crystallizes in the monoclinic P2/c space group. Y(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form distorted YO6 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 50-59°. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form WO6 octahedra that share corners with four equivalent Y(1)O6 octahedra, corners with four equivalent Cr(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-59°. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CrO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-56°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Y(1), one W(1), and one Cr(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Y(1), one W(1), and one Cr(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Y(1) and two equivalent W(1) atoms. is represented by the CIF file [CIF]
