Zr2OsCl crystallizes in the monoclinic Cm space group. Zr(1) is bonded in a 4-coordinate geometry to four equivalent Os(1) and two equivalent Cl(1) atoms. There are a spread of Zr(1)-Os(1) bond distances ranging from 2.60-3.30 Å. There is one shorter (2.36 Å) and one longer (2.65 Å) Zr(1)-Cl(1) bond length. Os(1) is bonded in a 8-coordinate geometry to eight equivalent Zr(1) atoms. Cl(1) is bonded in a square co-planar geometry to four equivalent Zr(1) atoms.
