Co Sb Sb Cl
CoSb2Cl crystallizes in the monoclinic Cm space group. Co(1) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1) and two equivalent Cl(1) atoms. Both Co(1)-Sb(1) bond lengths are 1.42 Å. There is one shorter (2.10 Å) and one longer (2.77 Å) Co(1)-Cl(1) bond length. Sb(1) is bonded in a 3-coordinate geometry to one Co(1) and two equivalent Cl(1) atoms. There is one shorter (2.41 Å) and one longer (2.78 Å) Sb(1)-Cl(1) bond length. Cl(1) is bonded in a 6-coordinate geometry to two equivalent Co(1) and four equivalent Sb(1) atoms.
