In In As P
In2AsP crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one In2AsP cluster. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 2-coordinate geometry to one As(1) and one P(1) atom. The In(1)-As(1) bond length is 0.74 Å. The In(1)-P(1) bond length is 0.95 Å. In the second In site, In(2) is bonded in a single-bond geometry to one As(1) atom. The In(2)-As(1) bond length is 0.74 Å. As(1) is bonded in a 3-coordinate geometry to one In(1), one In(2), and one P(1) atom. The As(1)-P(1) bond length is 1.12 Å. P(1) is bonded in a distorted single-bond geometry to one In(1) and one As(1) atom.
