MoV crystallizes in the triclinic P-1 space group. V(1) is bonded in a 8-coordinate geometry to seven equivalent V(1) and one Mo(1) atom. There is one shorter (2.70 Å) and six longer (2.71 Å) V(1)-V(1) bond lengths. The V(1)-Mo(1) bond length is 3.24 Å. Mo(1) is bonded in a distorted single-bond geometry to one V(1) and one Mo(1) atom. The Mo(1)-Mo(1) bond length is 0.98 Å.
