Sm7Pd3 crystallizes in the orthorhombic Cmc2_1 space group. There are five inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 3-coordinate geometry to one Pd(1) and two equivalent Pd(2) atoms. In the second Sm site, Sm(2) is bonded in a 3-coordinate geometry to one Pd(1) and two equivalent Pd(2) atoms. In the third Sm site, Sm(3) is bonded in a 3-coordinate geometry to one Pd(1) and two equivalent Pd(2) atoms. In the fourth Sm site, Sm(4) is bonded in a distorted water-like geometry to two equivalent Pd(2) atoms. In the fifth Sm site, Sm(5) is bonded in a distorted water-like geometry to one Pd(1) and one Pd(2) atom. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 6-coordinate geometry to one Sm(1), one Sm(2), two equivalent Sm(3), and two equivalent Sm(5) atoms. In the second Pd site, Pd(2) is bonded in a 6-coordinate geometry to one Sm(1), one Sm(2), one Sm(4), one Sm(5), and two equivalent Sm(3) atoms.
