Na Be Be Pt
NaBe2Pt crystallizes in the monoclinic Cm space group. Na(1) is bonded in a 13-coordinate geometry to four equivalent Na(1), one Be(1), four equivalent Be(2), and four equivalent Pt(1) atoms. All Na(1)-Na(1) bond lengths are 2.88 Å. The Na(1)-Be(1) bond length is 3.16 Å. There are a spread of Na(1)-Be(2) bond distances ranging from 2.91-3.24 Å. There are a spread of Na(1)-Pt(1) bond distances ranging from 3.04-3.36 Å. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 9-coordinate geometry to one Na(1), four equivalent Be(2), and four equivalent Pt(1) atoms. There are a spread of Be(1)-Be(2) bond distances ranging from 1.98-2.44 Å. There are a spread of Be(1)-Pt(1) bond distances ranging from 2.24-2.65 Å. In the second Be site, Be(2) is bonded in a 9-coordinate geometry to four equivalent Na(1), four equivalent Be(1), and one Pt(1) atom. The Be(2)-Pt(1) bond length is 2.21 Å. Pt(1) is bonded in a 13-coordinate geometry to four equivalent Na(1), one Be(2), four equivalent Be(1), and four equivalent Pt(1) atoms. All Pt(1)-Pt(1) bond lengths are 2.88 Å.
