Be2PtBi crystallizes in the trigonal R3m space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 4-coordinate geometry to three equivalent Pt(1) and one Bi(1) atom. All Be(1)-Pt(1) bond lengths are 2.71 Å. The Be(1)-Bi(1) bond length is 2.40 Å. In the second Be site, Be(2) is bonded in a distorted linear geometry to four equivalent Pt(1) and one Bi(1) atom. There is one shorter (2.40 Å) and three longer (2.93 Å) Be(2)-Pt(1) bond lengths. The Be(2)-Bi(1) bond length is 1.96 Å. Pt(1) is bonded in a 10-coordinate geometry to three equivalent Be(1), four equivalent Be(2), and three equivalent Bi(1) atoms. All Pt(1)-Bi(1) bond lengths are 2.71 Å. Bi(1) is bonded in a 2-coordinate geometry to one Be(1), one Be(2), and three equivalent Pt(1) atoms.
