The material described by VMoCrO7 crystallizes in the triclinic P-1 space group. V(1) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form VO4 tetrahedra that share corners with four equivalent Cr(1)O6 octahedra and  a cornercorner with one Mo(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 18-57°. Mo(1) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form MoO4 tetrahedra that share corners with two equivalent Cr(1)O6 octahedra and  a cornercorner with one V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 18-30°. Cr(1) is bonded to one O(2), one O(3), one O(4), one O(7), and two equivalent O(5) atoms to form CrO6 octahedra that share corners with two equivalent Mo(1)O4 tetrahedra, corners with four equivalent V(1)O4 tetrahedra, and  an edgeedge with one Cr(1)O6 octahedra. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Mo(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mo(1) and one Cr(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Mo(1) and one Cr(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(1) and one Cr(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one V(1) and two equivalent Cr(1) atoms. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one V(1) and one Mo(1) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one V(1) and one Cr(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
