VCo5 crystallizes in the trigonal R3m space group. V(1) is bonded in a single-bond geometry to one Co(2) and three equivalent Co(3) atoms. The V(1)-Co(2) bond length is 1.17 Å. All V(1)-Co(3) bond lengths are 2.98 Å. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 3-coordinate geometry to one Co(2), two equivalent Co(1), and three equivalent Co(3) atoms. The Co(1)-Co(2) bond length is 1.70 Å. Both Co(1)-Co(1) bond lengths are 1.72 Å. There are two shorter (2.52 Å) and one longer (2.98 Å) Co(1)-Co(3) bond length. In the second Co site, Co(2) is bonded in a single-bond geometry to one V(1) and three equivalent Co(1) atoms. In the third Co site, Co(3) is bonded in a 12-coordinate geometry to three equivalent V(1) and nine equivalent Co(1) atoms.
