In Cu Cu Sn
CuInCuSn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two 12053-87-1 molecules and two CuSn clusters. In each CuSn cluster, Cu(2) is bonded in a distorted single-bond geometry to one Sn(1) atom. The Cu(2)-Sn(1) bond length is 1.81 Å. Sn(1) is bonded in a distorted single-bond geometry to one Cu(2) atom.
