BiMnVO5 crystallizes in the triclinic P-1 space group. V(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form VO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra and corners with three equivalent Bi(1)O5 square pyramids. The corner-sharing octahedral tilt angles range from 49-55°. Mn(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form MnO6 octahedra that share  a cornercorner with one Bi(1)O5 square pyramid, corners with four equivalent V(1)O4 tetrahedra,  an edgeedge with one Mn(1)O6 octahedra, and edges with three equivalent Bi(1)O5 square pyramids. Bi(1) is bonded to one O(1), one O(2), one O(5), and two equivalent O(4) atoms to form distorted BiO5 square pyramids that share  a cornercorner with one Mn(1)O6 octahedra, corners with three equivalent V(1)O4 tetrahedra, edges with three equivalent Mn(1)O6 octahedra, and  an edgeedge with one Bi(1)O5 square pyramid. The corner-sharing octahedral tilt angles are 38°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(1), one Mn(1), and one Bi(1) atom.
