OsZn2Bi is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsZn2Bi clusters. Os(1) is bonded in a 3-coordinate geometry to two equivalent Zn(1) and one Bi(1) atom. Both Os(1)-Zn(1) bond lengths are 1.63 Å. The Os(1)-Bi(1) bond length is 1.81 Å. Zn(1) is bonded in a 2-coordinate geometry to one Os(1) and one Bi(1) atom. The Zn(1)-Bi(1) bond length is 1.63 Å. Bi(1) is bonded in a 3-coordinate geometry to one Os(1) and two equivalent Zn(1) atoms.
