KGeP2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KGeP2 clusters. K(1) is bonded in a single-bond geometry to one Ge(1) and one P(2) atom. The K(1)-Ge(1) bond length is 0.53 Å. The K(1)-P(2) bond length is 3.00 Å. Ge(1) is bonded in a single-bond geometry to one K(1) atom. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one P(2) atom. The P(1)-P(2) bond length is 1.25 Å. In the second P site, P(2) is bonded in a linear geometry to one K(1) and one P(1) atom.
