Nb Sn Cl Cl
NbSnCl2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NbSnCl2 clusters. Nb(1) is bonded in an L-shaped geometry to two equivalent Cl(1) atoms. Both Nb(1)-Cl(1) bond lengths are 0.87 Å. Sn(1) is bonded in a 2-coordinate geometry to two equivalent Cl(1) atoms. Both Sn(1)-Cl(1) bond lengths are 1.94 Å. Cl(1) is bonded in a single-bond geometry to one Nb(1) and one Sn(1) atom.
