SrPdIn4 crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 15-coordinate geometry to two equivalent Pd(1), three equivalent In(3), four equivalent In(2), and six equivalent In(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to two equivalent Sr(1), one In(3), and six equivalent In(1) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1), three equivalent Pd(1), and one In(2) atom. In the second In site, In(2) is bonded in a distorted q6 geometry to four equivalent Sr(1), two equivalent In(1), and four equivalent In(3) atoms. In the third In site, In(3) is bonded in a 2-coordinate geometry to three equivalent Sr(1), one Pd(1), and four equivalent In(2) atoms.
SrPdIn4 crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 15-coordinate geometry to two equivalent Pd(1), three equivalent In(3), four equivalent In(2), and six equivalent In(1) atoms. Both Sr(1)-Pd(1) bond lengths are 3.47 Å. There is one shorter (3.32 Å) and two longer (3.88 Å) Sr(1)-In(3) bond lengths. All Sr(1)-In(2) bond lengths are 3.65 Å. There are four shorter (3.39 Å) and two longer (3.62 Å) Sr(1)-In(1) bond lengths. Pd(1) is bonded in a 9-coordinate geometry to two equivalent Sr(1), one In(3), and six equivalent In(1) atoms. The Pd(1)-In(3) bond length is 2.68 Å. There are two shorter (2.74 Å) and four longer (2.83 Å) Pd(1)-In(1) bond lengths. There are three inequivalent In sites.
