VOsB4 crystallizes in the hexagonal P-6m2 space group. V(1) is bonded in a 8-coordinate geometry to two equivalent B(1) and six equivalent B(2) atoms. Os(1) is bonded in a 8-coordinate geometry to two equivalent B(2) and six equivalent B(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 7-coordinate geometry to one V(1), three equivalent Os(1), and three equivalent B(2) atoms. In the second B site, B(2) is bonded in a 7-coordinate geometry to three equivalent V(1), one Os(1), and three equivalent B(1) atoms.
