BeOs(Os)2 is lead oxide structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two BeOs clusters and two Os clusters. In each BeOs cluster, there are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a single-bond geometry to one Os(2) atom. The Be(1)-Os(2) bond length is 0.74 Å. In the second Be site, Be(2) is bonded in a 2-coordinate geometry to one Os(1) and one Os(2) atom. The Be(2)-Os(1) bond length is 1.23 Å. The Be(2)-Os(2) bond length is 1.57 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted single-bond geometry to one Be(2) atom. In the second Os site, Os(2) is bonded in a single-bond geometry to one Be(1) and one Be(2) atom. In each Os cluster, there are four inequivalent Os sites. In the first Os site, Os(3) is bonded in a 1-coordinate geometry to one Os(6) atom. The Os(3)-Os(6) bond length is 0.64 Å. In the second Os site, Os(4) is bonded in a distorted single-bond geometry to one Os(5) atom. The Os(4)-Os(5) bond length is 0.64 Å. In the third Os site, Os(5) is bonded in a distorted single-bond geometry to one Os(4) and one Os(6) atom. The Os(5)-Os(6) bond length is 1.34 Å. In the fourth Os site, Os(6) is bonded in a distorted L-shaped geometry to one Os(3) and one Os(5) atom.
