Co3V crystallizes in the monoclinic Cm space group. V(1) is bonded in an L-shaped geometry to two equivalent Co(1) and two equivalent Co(2) atoms. There is one shorter (1.95 Å) and one longer (2.38 Å) V(1)-Co(1) bond length. Both V(1)-Co(2) bond lengths are 0.83 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 6-coordinate geometry to two equivalent V(1) and four equivalent Co(2) atoms. There are two shorter (1.87 Å) and two longer (2.71 Å) Co(1)-Co(2) bond lengths. In the second Co site, Co(2) is bonded in a single-bond geometry to one V(1) and two equivalent Co(1) atoms.
