SrLa2Pt crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a single-bond geometry to one La(2) and one Pt(1) atom. The Sr(1)-La(2) bond length is 3.56 Å. The Sr(1)-Pt(1) bond length is 0.23 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded to one La(2), four equivalent La(1), and one Pt(1) atom to form distorted LaLa5Pt octahedra that share corners with four equivalent La(1)La5Pt octahedra, edges with four equivalent La(1)La5Pt octahedra, and edges with four equivalent La(2)SrLa5 octahedra. The corner-sharing octahedra are not tilted. The La(1)-La(2) bond length is 2.59 Å. All La(1)-La(1) bond lengths are 3.77 Å. The La(1)-Pt(1) bond length is 3.78 Å. In the second La site, La(2) is bonded to one Sr(1), one La(1), and four equivalent La(2) atoms to form distorted LaSrLa5 octahedra that share corners with four equivalent La(2)SrLa5 octahedra, edges with four equivalent La(1)La5Pt octahedra, and edges with four equivalent La(2)SrLa5 octahedra. The corner-sharing octahedra are not tilted. All La(2)-La(2) bond lengths are 3.77 Å. Pt(1) is bonded in a single-bond geometry to one Sr(1) and one La(1) atom.
