SrBePt2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrBePt2 cluster. Sr(1) is bonded in a single-bond geometry to one Be(1) and one Pt(2) atom. The Sr(1)-Be(1) bond length is 0.77 Å. The Sr(1)-Pt(2) bond length is 2.82 Å. Be(1) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one Pt(1) atom. The Be(1)-Pt(1) bond length is 1.05 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Be(1) atom. In the second Pt site, Pt(2) is bonded in a 1-coordinate geometry to one Sr(1) atom.
