GeP is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one GeP cluster. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one P(1) and one P(2) atom. The Ge(1)-P(1) bond length is 0.86 Å. The Ge(1)-P(2) bond length is 1.52 Å. In the second Ge site, Ge(2) is bonded in a single-bond geometry to one P(2) atom. The Ge(2)-P(2) bond length is 1.48 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Ge(1) atom. In the second P site, P(2) is bonded in a 2-coordinate geometry to one Ge(1) and one Ge(2) atom.
