Eu(IrP)2 crystallizes in the trigonal P3_221 space group. Eu(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 Eu(1) and four equivalent P(1) atoms. In the second Ir site, Ir(2) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and four equivalent P(1) atoms. P(1) is bonded to three equivalent Eu(1), two equivalent Ir(1), and two equivalent Ir(2) atoms to form a mixture of distorted corner, face, and edge-sharing PEu3Ir4 pentagonal bipyramids.
Eu(IrP)2 crystallizes in the trigonal P3_221 space group. Eu(1) is bonded in a 11-coordinate geometry to two equivalent Ir(2), three equivalent Ir(1), and six equivalent P(1) atoms. Both Eu(1)-Ir(2) bond lengths are 3.33 Å. There is one shorter (3.16 Å) and two longer (3.33 Å) Eu(1)-Ir(1) bond lengths. There are four shorter (3.06 Å) and two longer (3.16 Å) Eu(1)-P(1) bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 7-coordinate geometry to three equivalent Eu(1) and four equivalent P(1) atoms. There are two shorter (2.33 Å) and two longer (2.39 Å) Ir(1)-P(1) bond lengths. In the second Ir site, Ir(2) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and four equivalent P(1) atoms. There are two shorter (2.26 Å) and two longer (2.32 Å) Ir(2)-P(1) bond lengths. P(1) is bonded to three equivalent Eu(1), two equivalent Ir(1), and two equivalent Ir(2) atoms to form a mixture of distorted corner, face, and edge-sharing PEu3Ir4 pentagonal bipyramids.
