The structure described by V5Si3N 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 2-coordinate geometry to five equivalent Si(1) and two equivalent N(1) atoms. In the second V site, V(2) is bonded in a 8-coordinate geometry to two equivalent V(2) and six equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to four equivalent V(2) and five equivalent V(1) atoms. N(1) is bonded to six equivalent V(1) atoms to form face-sharing NV6 octahedra. is represented by the CIF file [CIF]
