The material structure described by Sm2Pt4P3 crystallizes in the tetragonal I-4m2 space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 15-coordinate geometry to four equivalent Pt(2), five equivalent Pt(1), two equivalent P(2), and four equivalent P(1) atoms. In the second Sm site, Sm(1) is bonded in a 15-coordinate geometry to four equivalent Pt(2), five equivalent Pt(1), two equivalent P(2), and four equivalent P(1) atoms. In the third Sm site, Sm(1) is bonded in a 15-coordinate geometry to four equivalent Pt(2), five equivalent Pt(1), two equivalent P(2), and four equivalent P(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 8-coordinate geometry to five Sm(1,1); one P(1); and two equivalent P(2) atoms. In the second Pt site, Pt(2) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent P(1) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Pt(1), and four equivalent Pt(2) atoms. In the second P site, P(1) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Pt(1), and four equivalent Pt(2) atoms. In the third P site, P(2) is bonded in a 8-coordinate geometry to four Sm(1,1) and four equivalent Pt(1) atoms. is represented by the CIF card [CIF]
