Be Be Bi Pt
Be2PtBi crystallizes in the monoclinic Cm space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 5-coordinate geometry to one Be(2), four equivalent Pt(1), and one Bi(1) atom. The Be(1)-Be(2) bond length is 1.93 Å. There are a spread of Be(1)-Pt(1) bond distances ranging from 2.06-2.47 Å. The Be(1)-Bi(1) bond length is 3.17 Å. In the second Be site, Be(2) is bonded in a 5-coordinate geometry to one Be(1), four equivalent Pt(1), and one Bi(1) atom. There are a spread of Be(2)-Pt(1) bond distances ranging from 2.40-2.75 Å. The Be(2)-Bi(1) bond length is 3.17 Å. Pt(1) is bonded in a 9-coordinate geometry to four equivalent Be(1), four equivalent Be(2), and one Bi(1) atom. The Pt(1)-Bi(1) bond length is 3.06 Å. Bi(1) is bonded in a 7-coordinate geometry to one Be(1), one Be(2), one Pt(1), and four equivalent Bi(1) atoms. All Bi(1)-Bi(1) bond lengths are 3.10 Å.
