K K Hg P
K2HgP crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one K2HgP cluster. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one P(1) atom. The K(1)-P(1) bond length is 2.03 Å. In the second K site, K(2) is bonded in a single-bond geometry to one Hg(1) atom. The K(2)-Hg(1) bond length is 1.27 Å. Hg(1) is bonded in a distorted bent 120 degrees geometry to one K(2) and one P(1) atom. The Hg(1)-P(1) bond length is 0.34 Å. P(1) is bonded in a distorted single-bond geometry to one K(1) and one Hg(1) atom.
