The crystal structure described by Sm2Pt3Ge5 crystallizes in the orthorhombic Ibam space group. Sm(1) is bonded in a 17-coordinate geometry to two equivalent Pt(1), five equivalent Pt(2), two equivalent Ge(1), four equivalent Ge(2), and four equivalent Ge(3) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to four equivalent Sm(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to five equivalent Sm(1), one Ge(3), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent Pt(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Pt(1), two equivalent Pt(2), and two equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Pt(2), two equivalent Pt(1), and two equivalent Ge(2) atoms. is represented by the CIF file [CIF]
