KHgP crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KHgP clusters. K(1) is bonded in a single-bond geometry to one Hg(1) and one P(1) atom. The K(1)-Hg(1) bond length is 3.41 Å. The K(1)-P(1) bond length is 1.05 Å. Hg(1) is bonded in a distorted single-bond geometry to one K(1) atom. P(1) is bonded in a single-bond geometry to one K(1) atom.
