The material described by V3(Co10B3)2 crystallizes in the cubic Fm-3m space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a cuboctahedral geometry to twelve equivalent Co(2) atoms. In the second V site, V(2) is bonded in a distorted tetrahedral geometry to four equivalent Co(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one V(2) and three equivalent B(1) atoms to form a mixture of corner and edge-sharing CoVB3 tetrahedra. In the second Co site, Co(2) is bonded in a 2-coordinate geometry to one V(1) and two equivalent B(1) atoms. B(1) is bonded in a 8-coordinate geometry to four equivalent Co(1) and four equivalent Co(2) atoms. is represented by the CIF file [CIF]
