Sr2PtSn is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2PtSn clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Pt(1) and one Sn(1) atom. The Sr(1)-Pt(1) bond length is 0.20 Å. The Sr(1)-Sn(1) bond length is 2.36 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Pt(1) atom. The Sr(2)-Pt(1) bond length is 0.20 Å. Pt(1) is bonded in a linear geometry to one Sr(1) and one Sr(2) atom. Sn(1) is bonded in a single-bond geometry to one Sr(1) atom.
