BeVOs crystallizes in the trigonal R3m space group. Be(1) is bonded to one V(1) and three equivalent Os(1) atoms to form distorted BeVOs3 tetrahedra that share corners with three equivalent V(1)BeOs3 tetrahedra, corners with six equivalent Be(1)VOs3 tetrahedra, and edges with three equivalent V(1)BeOs3 tetrahedra. The Be(1)-V(1) bond length is 1.83 Å. All Be(1)-Os(1) bond lengths are 2.40 Å. V(1) is bonded to one Be(1) and three equivalent Os(1) atoms to form distorted VBeOs3 tetrahedra that share corners with three equivalent Be(1)VOs3 tetrahedra, corners with six equivalent V(1)BeOs3 tetrahedra, and edges with three equivalent Be(1)VOs3 tetrahedra. All V(1)-Os(1) bond lengths are 2.40 Å. Os(1) is bonded in a distorted hexagonal planar geometry to three equivalent Be(1) and three equivalent V(1) atoms.
