Nb V Co Co
NbVCo2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NbVCo2 clusters. Nb(1) is bonded in a 2-coordinate geometry to two equivalent Co(1) atoms. Both Nb(1)-Co(1) bond lengths are 1.27 Å. V(1) is bonded in a 2-coordinate geometry to two equivalent Co(1) atoms. Both V(1)-Co(1) bond lengths are 0.78 Å. Co(1) is bonded in a 3-coordinate geometry to one Nb(1), one V(1), and one Co(1) atom. The Co(1)-Co(1) bond length is 0.49 Å.
