The material described by Sr(IrP)2 crystallizes in the trigonal P3_221 space group. Sr(1) is bonded in a 11-coordinate geometry to two equivalent Ir(2), three equivalent Ir(1), and six equivalent P(1) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1) and four equivalent P(1) atoms. In the second Ir site, Ir(2) is bonded in a 6-coordinate geometry to two equivalent Sr(1) and four equivalent P(1) atoms. P(1) is bonded to three equivalent Sr(1), two equivalent Ir(1), and two equivalent Ir(2) atoms to form a mixture of distorted edge, corner, and face-sharing PSr3Ir4 pentagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
