The compound described by IrV crystallizes in the orthorhombic Cmmm space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to four equivalent V(3), four equivalent Ir(1), and four equivalent Ir(2) atoms to form a mixture of distorted face and corner-sharing VV4Ir8 cuboctahedra. In the second V site, V(2) is bonded in a body-centered cubic geometry to four equivalent Ir(1) and four equivalent Ir(2) atoms. In the third V site, V(3) is bonded in a 8-coordinate geometry to two equivalent V(1), four equivalent Ir(1), and four equivalent Ir(2) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent V(1), two equivalent V(2), and four equivalent V(3) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to two equivalent V(1), two equivalent V(2), and four equivalent V(3) atoms. is represented by the CIF card [CIF]
