The structure described by Li4SrP2 crystallizes in the trigonal R-3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a trigonal planar geometry to three equivalent P(1) atoms. In the second Li site, Li(2) is bonded in a 4-coordinate geometry to four equivalent P(1) atoms. Sr(1) is bonded to six equivalent P(1) atoms to form distorted edge-sharing SrP6 octahedra. P(1) is bonded in a 10-coordinate geometry to three equivalent Li(1), four equivalent Li(2), and three equivalent Sr(1) atoms. is represented by the CIF file [CIF]
