Hf Sb Sb Cl
HfSb2Cl is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfSb2Cl clusters. Hf(1) is bonded in a distorted single-bond geometry to one Cl(1) atom. The Hf(1)-Cl(1) bond length is 2.20 Å. Sb(1) is bonded in a single-bond geometry to one Cl(1) atom. The Sb(1)-Cl(1) bond length is 1.26 Å. Cl(1) is bonded in a 3-coordinate geometry to one Hf(1) and two equivalent Sb(1) atoms.
