SrCr2Pt crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Cr(2), and four equivalent Cr(1) atoms. All Sr(1)-Sr(1) bond lengths are 2.74 Å. The Sr(1)-Cr(2) bond length is 3.97 Å. There are a spread of Sr(1)-Cr(1) bond distances ranging from 3.32-3.86 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 1-coordinate geometry to four equivalent Sr(1) and one Pt(1) atom. The Cr(1)-Pt(1) bond length is 1.86 Å. In the second Cr site, Cr(2) is bonded in a 1-coordinate geometry to one Sr(1) and one Pt(1) atom. The Cr(2)-Pt(1) bond length is 1.86 Å. Pt(1) is bonded in a 2-coordinate geometry to one Cr(1) and one Cr(2) atom.
