InAs2P is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two InAs2P clusters. In(1) is bonded in a 2-coordinate geometry to two equivalent As(1) atoms. Both In(1)-As(1) bond lengths are 1.63 Å. As(1) is bonded in a distorted single-bond geometry to one In(1), one As(1), and one P(1) atom. The As(1)-As(1) bond length is 0.39 Å. The As(1)-P(1) bond length is 0.93 Å. P(1) is bonded in a 2-coordinate geometry to two equivalent As(1) atoms.
