In Sn Sn Sn
InSn3 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two InSn3 clusters. In(1) is bonded in a distorted single-bond geometry to one Sn(2) and two equivalent Sn(1) atoms. The In(1)-Sn(2) bond length is 1.14 Å. Both In(1)-Sn(1) bond lengths are 1.93 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one In(1) atom. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one In(1) atom.
