InGe2P crystallizes in the monoclinic Cm space group. In(1) is bonded in a distorted water-like geometry to one Ge(2) and three equivalent Ge(1) atoms. The In(1)-Ge(2) bond length is 2.43 Å. There is one shorter (2.43 Å) and two longer (3.22 Å) In(1)-Ge(1) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to three equivalent In(1) and one P(1) atom. The Ge(1)-P(1) bond length is 2.84 Å. In the second Ge site, Ge(2) is bonded in a 1-coordinate geometry to one In(1) and one P(1) atom. The Ge(2)-P(1) bond length is 1.72 Å. P(1) is bonded in a distorted single-bond geometry to one Ge(1) and one Ge(2) atom.
