Sr2CrP crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2CrP clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Cr(1) atom. The Sr(1)-Cr(1) bond length is 1.71 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one P(1) atom. The Sr(2)-P(1) bond length is 0.48 Å. Cr(1) is bonded in a linear geometry to one Sr(1) and one P(1) atom. The Cr(1)-P(1) bond length is 1.38 Å. P(1) is bonded in a distorted bent 120 degrees geometry to one Sr(2) and one Cr(1) atom.
