BeOs4Ga crystallizes in the trigonal R3m space group. Be(1) is bonded in a trigonal pyramidal geometry to three equivalent Os(1) and one Ga(1) atom. All Be(1)-Os(1) bond lengths are 2.41 Å. The Be(1)-Ga(1) bond length is 2.38 Å. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded in a 6-coordinate geometry to three equivalent Os(1) and three equivalent Ga(1) atoms. All Os(2)-Os(1) bond lengths are 1.65 Å. All Os(2)-Ga(1) bond lengths are 3.02 Å. In the second Os site, Os(1) is bonded in a 5-coordinate geometry to one Be(1), one Os(2), two equivalent Os(1), and one Ga(1) atom. Both Os(1)-Os(1) bond lengths are 0.95 Å. The Os(1)-Ga(1) bond length is 2.07 Å. Ga(1) is bonded in a 7-coordinate geometry to one Be(1), three equivalent Os(1), and three equivalent Os(2) atoms.
