BaOs2Ga crystallizes in the triclinic P1 space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent Os(1) and four equivalent Ga(1) atoms. There are a spread of Ba(1)-Os(1) bond distances ranging from 2.59-3.40 Å. There are a spread of Ba(1)-Ga(1) bond distances ranging from 2.76-3.14 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to four equivalent Ba(1) atoms. In the second Os site, Os(2) is bonded in a 2-coordinate geometry to two equivalent Ga(1) atoms. There is one shorter (2.59 Å) and one longer (2.61 Å) Os(2)-Ga(1) bond length. Ga(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1) and two equivalent Os(2) atoms.
