Pd4Pr3 crystallizes in the trigonal R-3 space group. Pr(1) is bonded in a 9-coordinate geometry to one Pd(1), one Pd(2), and seven equivalent Pd(3) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms. In the second Pd site, Pd(2) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms. In the third Pd site, Pd(3) is bonded in a 10-coordinate geometry to seven equivalent Pr(1) and three equivalent Pd(3) atoms.
Pd4Pr3 crystallizes in the trigonal R-3 space group. Pr(1) is bonded in a 9-coordinate geometry to one Pd(1), one Pd(2), and seven equivalent Pd(3) atoms. The Pr(1)-Pd(1) bond length is 2.99 Å. The Pr(1)-Pd(2) bond length is 3.05 Å. There are a spread of Pr(1)-Pd(3) bond distances ranging from 2.92-3.39 Å. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms. In the second Pd site, Pd(2) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms. In the third Pd site, Pd(3) is bonded in a 10-coordinate geometry to seven equivalent Pr(1) and three equivalent Pd(3) atoms. There is one shorter (2.92 Å) and two longer (3.03 Å) Pd(3)-Pd(3) bond lengths.
