BWOs crystallizes in the trigonal R3m space group. W(1) is bonded in a single-bond geometry to four equivalent Os(1) and one B(1) atom. There are three shorter (2.23 Å) and one longer (2.78 Å) W(1)-Os(1) bond length. The W(1)-B(1) bond length is 0.51 Å. Os(1) is bonded to four equivalent W(1) and three equivalent B(1) atoms to form a mixture of corner and edge-sharing OsB3W4 hexagonal pyramids. All Os(1)-B(1) bond lengths are 2.21 Å. B(1) is bonded in a single-bond geometry to one W(1) and three equivalent Os(1) atoms.
