K Ge Ge P
KGe2P crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KGe2P clusters. K(1) is bonded in a single-bond geometry to one Ge(1) and one P(1) atom. The K(1)-Ge(1) bond length is 2.73 Å. The K(1)-P(1) bond length is 0.82 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a single-bond geometry to one K(1) atom. In the second Ge site, Ge(2) is bonded in a single-bond geometry to one P(1) atom. The Ge(2)-P(1) bond length is 1.43 Å. P(1) is bonded in a distorted single-bond geometry to one K(1) and one Ge(2) atom.
