V2CrO6 crystallizes in the triclinic P-1 space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(3), one O(5), and one O(6) atom to form VO4 tetrahedra that share corners with three equivalent Cr(1)O6 octahedra and corners with two equivalent V(2)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 23-60°. In the second V site, V(2) is bonded to one O(2), one O(5), one O(6), and two equivalent O(4) atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent Cr(1)O6 octahedra, corners with two equivalent V(1)O4 tetrahedra,  an edgeedge with one Cr(1)O6 octahedra, and  an edgeedge with one V(2)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 35-39°. 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 three equivalent V(1)O4 tetrahedra, corners with two equivalent V(2)O5 trigonal bipyramids, edges with two equivalent Cr(1)O6 octahedra, and  an edgeedge with one V(2)O5 trigonal bipyramid. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(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 V(2) and two equivalent Cr(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one Cr(1) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to two equivalent V(2) and one Cr(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one V(1) and one V(2) atom.
