Sr Co Sn
SrCoSn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrCoSn clusters. Sr(1) is bonded in a single-bond geometry to one Co(1) atom. The Sr(1)-Co(1) bond length is 0.62 Å. Co(1) is bonded in a distorted single-bond geometry to one Sr(1) and one Sn(1) atom. The Co(1)-Sn(1) bond length is 1.41 Å. Sn(1) is bonded in a single-bond geometry to one Co(1) atom.
