Sm7Pt3 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 three equivalent Pt(1,2) atoms. In the second Sm site, Sm(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1,2) atoms. In the third Sm site, Sm(3) is bonded in a 3-coordinate geometry to three equivalent Pt(1,2) atoms. In the fourth Sm site, Sm(4) is bonded in a distorted water-like geometry to two equivalent Pt(1,2) atoms. In the fifth Sm site, Sm(5) is bonded in a distorted water-like geometry to two equivalent Pt(1,2) atoms. Pt(1,2) is bonded in a 6-coordinate geometry to one Sm(1), one Sm(2), two equivalent Sm(3), and two equivalent Sm(5) atoms.
Sm7Pt3 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 three equivalent Pt(1,2) atoms. All Sm(1)-Pt(1,2) bond lengths are 2.93 Å. In the second Sm site, Sm(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1,2) atoms. There are two shorter (2.94 Å) and one longer (3.03 Å) Sm(2)-Pt(1,2) bond length. In the third Sm site, Sm(3) is bonded in a 3-coordinate geometry to three equivalent Pt(1,2) atoms. There are two shorter (2.94 Å) and one longer (3.04 Å) Sm(3)-Pt(1,2) bond length. In the fourth Sm site, Sm(4) is bonded in a distorted water-like geometry to two equivalent Pt(1,2) atoms. Both Sm(4)-Pt(1,2) bond lengths are 2.90 Å. In the fifth Sm site, Sm(5) is bonded in a distorted water-like geometry to two equivalent Pt(1,2) atoms. There is one shorter (2.89 Å) and one longer (2.90 Å) Sm(5)-Pt(1,2) bond length. Pt(1,2) is bonded in a 6-coordinate geometry to one Sm(1), one Sm(2), two equivalent Sm(3), and two equivalent Sm(5) atoms.
