BiSb2P is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BiSb2P clusters. Bi(1) is bonded in an L-shaped geometry to two equivalent Sb(1) atoms. Both Bi(1)-Sb(1) bond lengths are 0.75 Å. Sb(1) is bonded in a distorted single-bond geometry to one Bi(1) and one P(1) atom. The Sb(1)-P(1) bond length is 2.07 Å. P(1) is bonded in a 2-coordinate geometry to two equivalent Sb(1) atoms.
