Sr Ir Pd Pd
SrIrPd2 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 2-coordinate geometry to two equivalent Ir(1), one Pd(1), and one Pd(2) atom. There is one shorter (3.47 Å) and one longer (3.54 Å) Sr(1)-Ir(1) bond length. The Sr(1)-Pd(1) bond length is 1.86 Å. The Sr(1)-Pd(2) bond length is 1.89 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 12-coordinate geometry to two equivalent Sr(1), four equivalent Ir(1), three equivalent Pd(1), and three equivalent Pd(2) atoms. All Ir(1)-Ir(1) bond lengths are 3.36 Å. There is one shorter (2.85 Å) and two longer (3.49 Å) Ir(1)-Pd(1) bond lengths. There is one shorter (2.85 Å) and two longer (3.49 Å) Ir(1)-Pd(2) bond lengths. In the second Ir site, Ir(1) is bonded in a 12-coordinate geometry to two equivalent Sr(1), four equivalent Ir(1), three equivalent Pd(1), and three equivalent Pd(2) atoms. There is one shorter (3.47 Å) and one longer (3.54 Å) Ir(1)-Sr(1) bond length. There is one shorter (2.85 Å) and two longer (3.49 Å) Ir(1)-Pd(1) bond lengths. There is one shorter (2.85 Å) and two longer (3.49 Å) Ir(1)-Pd(2) bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted single-bond geometry to one Sr(1) and three Ir(1,1) atoms. In the second Pd site, Pd(2) is bonded in a distorted single-bond geometry to one Sr(1) and three Ir(1,1) atoms.
