SrPtCl2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrPtCl2 clusters. Sr(1) is bonded in a distorted L-shaped geometry to two equivalent Cl(1) atoms. Both Sr(1)-Cl(1) bond lengths are 1.73 Å. Pt(1) is bonded in an L-shaped geometry to two equivalent Cl(1) atoms. Both Pt(1)-Cl(1) bond lengths are 1.73 Å. Cl(1) is bonded in a 2-coordinate geometry to one Sr(1) and one Pt(1) atom.
