OsB2 crystallizes in the triclinic P-1 space group. Os(1) is bonded in a 5-coordinate geometry to three equivalent B(1) and three equivalent B(2) atoms. There are a spread of Os(1)-B(1) bond distances ranging from 1.81-2.00 Å. There are a spread of Os(1)-B(2) bond distances ranging from 2.07-2.62 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 4-coordinate geometry to three equivalent Os(1) and one B(2) atom. The B(1)-B(2) bond length is 1.64 Å. In the second B site, B(2) is bonded in a 5-coordinate geometry to three equivalent Os(1), one B(1), and one B(2) atom. The B(2)-B(2) bond length is 2.11 Å.
