The crystal structure described by Pr3Pt7Sb4 crystallizes in the monoclinic C2/m space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 12-coordinate geometry to two equivalent Pt(1), two equivalent Pt(2), two equivalent Pt(3), two equivalent Pt(4), two equivalent Sb(1), and three equivalent Sb(2) atoms. In the second Pr site, Pr(2) is bonded in a 16-coordinate geometry to two equivalent Pt(3), four equivalent Pt(1), four equivalent Pt(2), two equivalent Sb(1), and four equivalent Sb(2) atoms. There are four inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to two equivalent Pr(1), two equivalent Pr(2), one Pt(2), one Sb(2), and three equivalent Sb(1) atoms. In the second Pt site, Pt(2) is bonded in a 12-coordinate geometry to two equivalent Pr(1), two equivalent Pr(2), one Pt(1), two equivalent Pt(3), two equivalent Pt(4), one Sb(2), and two equivalent Sb(1) atoms. In the third Pt site, Pt(3) is bonded in a 6-coordinate geometry to one Pr(2), two equivalent Pr(1), two equivalent Pt(2), and three equivalent Sb(2) atoms. In the fourth Pt site, Pt(4) is bonded in a 6-coordinate geometry to four equivalent Pr(1), four equivalent Pt(2), and two equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to one Pr(2), two equivalent Pr(1), one Pt(4), two equivalent Pt(2), and three equivalent Pt(1) atoms. In the second Sb site, Sb(2) is bonded in a 10-coordinate geometry to two equivalent Pr(2), three equivalent Pr(1), one Pt(1), one Pt(2), and three equivalent Pt(3) atoms. is represented by the CIF file [CIF]
