K Cr P P
KCrP2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KCrP2 clusters. K(1) is bonded in a single-bond geometry to one Cr(1) and one P(2) atom. The K(1)-Cr(1) bond length is 0.84 Å. The K(1)-P(2) bond length is 2.68 Å. Cr(1) is bonded in a linear geometry to one K(1) and one P(1) atom. The Cr(1)-P(1) bond length is 1.22 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Cr(1) atom. In the second P site, P(2) is bonded in a single-bond geometry to one K(1) atom.
