Pr12Pt7In crystallizes in the tetragonal I4/mcm space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 6-coordinate geometry to one Pt(2), one Pt(3), three equivalent Pt(1), and one In(1) atom. In the second Pr site, Pr(2) is bonded in a distorted linear geometry to two equivalent Pt(1) and three equivalent Pt(2) atoms. In the third Pr site, Pr(3) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Pt(2) atoms. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 8-coordinate geometry to one Pr(2), one Pr(3), and six equivalent Pr(1) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to two equivalent Pr(3), three equivalent Pr(2), and four equivalent Pr(1) atoms. In the third Pt site, Pt(3) is bonded in a 8-coordinate geometry to eight equivalent Pr(1) atoms. In(1) is bonded in a body-centered cubic geometry to eight equivalent Pr(1) atoms.
