The structure described by V5Se4 is Titanium telluride structured and crystallizes in the tetragonal I4/m space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a distorted square co-planar geometry to four equivalent Se(1) atoms. In the second V site, V(2) is bonded to five equivalent Se(1) atoms to form a mixture of distorted edge and corner-sharing VSe5 square pyramids. Se(1) is bonded in a 6-coordinate geometry to one V(1) and five equivalent V(2) atoms. is represented by the CIF file [CIF]
