InPCl2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two InPCl2 clusters. In(1) is bonded in a distorted single-bond geometry to one P(1) and one Cl(1) atom. The In(1)-P(1) bond length is 2.59 Å. The In(1)-Cl(1) bond length is 1.57 Å. P(1) is bonded in a single-bond geometry to one In(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one In(1) and one Cl(2) atom. The Cl(1)-Cl(2) bond length is 1.83 Å. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Cl(1) atom.
