The material described by Al8V5 is gamma-brass structured and crystallizes in the cubic I-43m space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 13-coordinate geometry to one V(1), two equivalent V(2), two equivalent Al(1), and eight equivalent Al(2) atoms. In the second V site, V(2) is bonded in a 12-coordinate geometry to three equivalent V(1), three equivalent Al(1), and six equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 12-coordinate geometry to three equivalent V(1), three equivalent V(2), three equivalent Al(1), and three equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a 11-coordinate geometry to two equivalent V(2), four equivalent V(1), one Al(1), and four equivalent Al(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
