InP2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one InP2 cluster. There are four inequivalent In sites. In the first In site, In(1) is bonded in a 3-coordinate geometry to one In(4), one P(2), and one P(3) atom. The In(1)-In(4) bond length is 1.41 Å. The In(1)-P(2) bond length is 2.03 Å. The In(1)-P(3) bond length is 1.81 Å. In the second In site, In(2) is bonded in a 5-coordinate geometry to one In(3), one P(3), one P(4), one P(5), and one P(6) atom. The In(2)-In(3) bond length is 1.41 Å. The In(2)-P(3) bond length is 1.92 Å. The In(2)-P(4) bond length is 1.81 Å. The In(2)-P(5) bond length is 1.84 Å. The In(2)-P(6) bond length is 1.34 Å. In the third In site, In(3) is bonded in a 2-coordinate geometry to one In(2) and one P(4) atom. The In(3)-P(4) bond length is 1.81 Å. In the fourth In site, In(4) is bonded in a 5-coordinate geometry to one In(1), one P(3), one P(4), one P(7), and one P(8) atom. The In(4)-P(3) bond length is 1.81 Å. The In(4)-P(4) bond length is 1.92 Å. The In(4)-P(7) bond length is 1.34 Å. The In(4)-P(8) bond length is 1.84 Å. There are eight inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one P(2) atom. The P(1)-P(2) bond length is 2.02 Å. In the second P site, P(2) is bonded in a distorted single-bond geometry to one In(1) and one P(1) atom. In the third P site, P(3) is bonded in a 4-coordinate geometry to one In(1), one In(2), one In(4), and one P(6) atom. The P(3)-P(6) bond length is 1.54 Å. In the fourth P site, P(4) is bonded in a 4-coordinate geometry to one In(2), one In(3), one In(4), and one P(7) atom. The P(4)-P(7) bond length is 1.54 Å. In the fifth P site, P(5) is bonded in a 2-coordinate geometry to one In(2) and one P(6) atom. The P(5)-P(6) bond length is 1.21 Å. In the sixth P site, P(6) is bonded in a distorted single-bond geometry to one In(2), one P(3), and one P(5) atom. In the seventh P site, P(7) is bonded in a distorted single-bond geometry to one In(4), one P(4), and one P(8) atom. The P(7)-P(8) bond length is 1.21 Å. In the eighth P site, P(8) is bonded in a 2-coordinate geometry to one In(4) and one P(7) atom.
