The material described by Pr3Pt4 crystallizes in the trigonal R-3 space group. Pr(1) is bonded in a 9-coordinate geometry to one Pt(2), one Pt(3), and seven equivalent Pt(1) atoms. There are three inequivalent Pt sites. In the first Pt site, Pt(3) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms. In the second Pt site, Pt(1) is bonded in a 10-coordinate geometry to seven equivalent Pr(1) and three equivalent Pt(1) atoms. In the third Pt site, Pt(2) is bonded in a distorted octahedral geometry to six equivalent Pr(1) atoms. is represented by the CIF card [CIF]
