In the third V site, V(3) is bonded in a 6-coordinate geometry to two equivalent B(1), two equivalent B(2), and two equivalent B(3) atoms. In the fourth V site, V(4) is bonded in a 6-coordinate geometry to two equivalent B(1), two equivalent B(2), and two equivalent B(4) atoms. In the fifth V site, V(5) is bonded in a square co-planar geometry to two equivalent B(1) and two equivalent B(3) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted square co-planar geometry to two equivalent B(2) and two equivalent B(4) atoms. In the second Cr site, Cr(2) is bonded in a distorted rectangular see-saw-like geometry to one B(1), one B(2), one B(3), and one B(4) atom. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to one V(5), two equivalent V(1), two equivalent V(3), two equivalent V(4), one Cr(2), and one B(2) atom. In the second B site, B(2) is bonded in a 9-coordinate geometry to two equivalent V(2), two equivalent V(3), two equivalent V(4), one Cr(1), one Cr(2), and one B(1) atom. In the third B site, B(3) is bonded in a 9-coordinate geometry to one V(5), two equivalent V(3), four equivalent V(1), one Cr(2), and one B(3) atom. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to two equivalent V(4), four equivalent V(2), one Cr(1), one Cr(2), and one B(4) atom. is represented by the CIF file [CIF]
