(Os)2BPb is alpha carbon monoxide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one boron;lead molecule and one Os cluster. In the Os cluster, Os(1,2) is bonded in a single-bond geometry to one Os(1,2) atom. The Os(1,2)-Os(1,2) bond length is 1.46 Å.
