BaBe2Pt crystallizes in the monoclinic Cm space group. Ba(1) is bonded in a 4-coordinate geometry to one Be(2) and three equivalent Be(1) atoms. The Ba(1)-Be(2) bond length is 2.87 Å. There is one shorter (2.63 Å) and two longer (3.07 Å) Ba(1)-Be(1) bond lengths. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a single-bond geometry to three equivalent Ba(1) and one Pt(1) atom. The Be(1)-Pt(1) bond length is 1.15 Å. In the second Be site, Be(2) is bonded in a 4-coordinate geometry to one Ba(1) and three equivalent Pt(1) atoms. There is one shorter (2.13 Å) and two longer (2.65 Å) Be(2)-Pt(1) bond lengths. Pt(1) is bonded in a distorted single-bond geometry to one Be(1) and three equivalent Be(2) atoms.
