BeLuPt2 crystallizes in the trigonal R3m space group. Be(1) is bonded in a 5-coordinate geometry to one Lu(1), one Pt(1), and three equivalent Pt(2) atoms. The Be(1)-Lu(1) bond length is 2.14 Å. The Be(1)-Pt(1) bond length is 2.33 Å. All Be(1)-Pt(2) bond lengths are 2.72 Å. Lu(1) is bonded in a 7-coordinate geometry to one Be(1), three equivalent Pt(1), and three equivalent Pt(2) atoms. All Lu(1)-Pt(1) bond lengths are 2.72 Å. All Lu(1)-Pt(2) bond lengths are 2.72 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 1-coordinate geometry to one Be(1), three equivalent Lu(1), and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 2.14 Å. In the second Pt site, Pt(2) is bonded in a 7-coordinate geometry to three equivalent Be(1), three equivalent Lu(1), and one Pt(1) atom.
