Ca(IrP)2 crystallizes in the trigonal P3_221 space group. Ca(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 7-coordinate geometry to three equivalent Ca(1) and four equivalent P(1) atoms. In the second Ir site, Ir(2) is bonded in a 6-coordinate geometry to two equivalent Ca(1) and four equivalent P(1) atoms. P(1) is bonded to three equivalent Ca(1), two equivalent Ir(1), and two equivalent Ir(2) atoms to form a mixture of distorted edge, corner, and face-sharing PCa3Ir4 pentagonal bipyramids.
Ca(IrP)2 crystallizes in the trigonal P3_221 space group. Ca(1) is bonded in a 11-coordinate geometry to two equivalent Ir(2), three equivalent Ir(1), and six equivalent P(1) atoms. Both Ca(1)-Ir(2) bond lengths are 3.30 Å. There is one shorter (3.10 Å) and two longer (3.29 Å) Ca(1)-Ir(1) bond lengths. There are a spread of Ca(1)-P(1) bond distances ranging from 3.00-3.15 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 7-coordinate geometry to three equivalent Ca(1) and four equivalent P(1) atoms. There are two shorter (2.34 Å) and two longer (2.36 Å) Ir(1)-P(1) bond lengths. In the second Ir site, Ir(2) is bonded in a 6-coordinate geometry to two equivalent Ca(1) and four equivalent P(1) atoms. There are two shorter (2.24 Å) and two longer (2.31 Å) Ir(2)-P(1) bond lengths. P(1) is bonded to three equivalent Ca(1), two equivalent Ir(1), and two equivalent Ir(2) atoms to form a mixture of distorted edge, corner, and face-sharing PCa3Ir4 pentagonal bipyramids.
