AlGeP2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AlGeP2 cluster. Al(1) is bonded in a 3-coordinate geometry to one Ge(1), one P(1), and one P(2) atom. The Al(1)-Ge(1) bond length is 1.34 Å. The Al(1)-P(1) bond length is 1.57 Å. The Al(1)-P(2) bond length is 1.34 Å. Ge(1) is bonded in a 2-coordinate geometry to one Al(1) and one P(2) atom. The Ge(1)-P(2) bond length is 1.06 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Al(1) atom. In the second P site, P(2) is bonded in a 2-coordinate geometry to one Al(1) and one Ge(1) atom.
