PrPt3B crystallizes in the tetragonal P4mm space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Pt(2), eight equivalent Pt(1), and four equivalent B(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to four equivalent Pr(1) and two equivalent B(1) atoms. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to four equivalent Pr(1) and one B(1) atom. B(1) is bonded in a 5-coordinate geometry to four equivalent Pr(1), one Pt(2), and four equivalent Pt(1) atoms.
PrPt3B crystallizes in the tetragonal P4mm space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Pt(2), eight equivalent Pt(1), and four equivalent B(1) atoms. All Pr(1)-Pt(2) bond lengths are 2.92 Å. There are four shorter (3.19 Å) and four longer (3.32 Å) Pr(1)-Pt(1) bond lengths. All Pr(1)-B(1) bond lengths are 3.23 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to four equivalent Pr(1) and two equivalent B(1) atoms. Both Pt(1)-B(1) bond lengths are 2.23 Å. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to four equivalent Pr(1) and one B(1) atom. The Pt(2)-B(1) bond length is 2.11 Å. B(1) is bonded in a 5-coordinate geometry to four equivalent Pr(1), one Pt(2), and four equivalent Pt(1) atoms.
