K2CdP crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2CdP clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 1-coordinate geometry to one Cd(1) atom. The K(1)-Cd(1) bond length is 3.83 Å. In the second K site, K(2) is bonded in a single-bond geometry to one P(1) atom. The K(2)-P(1) bond length is 1.87 Å. Cd(1) is bonded in a distorted single-bond geometry to one K(1) and one P(1) atom. The Cd(1)-P(1) bond length is 1.96 Å. P(1) is bonded in a linear geometry to one K(2) and one Cd(1) atom.
