Be2NbPt is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Be2NbPt clusters. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a linear geometry to one Be(2) and one Nb(1) atom. The Be(1)-Be(2) bond length is 0.60 Å. The Be(1)-Nb(1) bond length is 0.06 Å. In the second Be site, Be(2) is bonded in a single-bond geometry to one Be(1) atom. Nb(1) is bonded in a single-bond geometry to one Be(1) and one Pt(1) atom. The Nb(1)-Pt(1) bond length is 2.21 Å. Pt(1) is bonded in a single-bond geometry to one Nb(1) atom.
