The crystal structure described by WCr3O8 is Rutile-derived structured and crystallizes in the hexagonal P6_3mc space group. W(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form WO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and edges with three equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. Cr(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form CrO6 octahedra that share corners with two equivalent W(1)O6 octahedra,  an edgeedge with one W(1)O6 octahedra, and edges with four equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one W(1) and two equivalent Cr(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one W(1) and two equivalent Cr(1) atoms. In the third O site, O(3) is bonded in a distorted T-shaped geometry to three equivalent Cr(1) atoms. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to three equivalent Cr(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
