Bi Os Cl Cl
OsBiCl2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsBiCl2 clusters. Os(1) is bonded in a 3-coordinate geometry to one Bi(1) and two equivalent Cl(1) atoms. The Os(1)-Bi(1) bond length is 1.03 Å. Both Os(1)-Cl(1) bond lengths are 1.39 Å. Bi(1) is bonded in a 3-coordinate geometry to one Os(1) and two equivalent Cl(1) atoms. Both Bi(1)-Cl(1) bond lengths are 1.39 Å. Cl(1) is bonded in a 3-coordinate geometry to one Os(1), one Bi(1), and one Cl(1) atom. The Cl(1)-Cl(1) bond length is 1.03 Å.
