K K Be Pt
K2BePt is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2BePt clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Pt(1) atom. The K(1)-Pt(1) bond length is 0.36 Å. In the second K site, K(2) is bonded in a single-bond geometry to one Be(1) and one Pt(1) atom. The K(2)-Be(1) bond length is 2.85 Å. The K(2)-Pt(1) bond length is 0.36 Å. Be(1) is bonded in a single-bond geometry to one K(2) atom. Pt(1) is bonded in a linear geometry to one K(1) and one K(2) atom.
