The structure described by V5CAs3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 6-coordinate geometry to six equivalent As(1) atoms. In the second V site, V(2) is bonded in a 2-coordinate geometry to two equivalent C(1) and five equivalent As(1) atoms. C(1) is bonded to six equivalent V(2) atoms to form face-sharing CV6 octahedra. As(1) is bonded in a 9-coordinate geometry to four equivalent V(1) and five equivalent V(2) atoms. is represented by the CIF file [CIF]
