K K Cr Pt
K2CrPt crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2CrPt clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Cr(1) atom. The K(1)-Cr(1) bond length is 1.08 Å. In the second K site, K(2) is bonded in a distorted single-bond geometry to one Pt(1) atom. The K(2)-Pt(1) bond length is 3.15 Å. Cr(1) is bonded in a distorted single-bond geometry to one K(1) and one Pt(1) atom. The Cr(1)-Pt(1) bond length is 2.07 Å. Pt(1) is bonded in a 2-coordinate geometry to one K(2) and one Cr(1) atom.
