Y3Pd4 crystallizes in the trigonal R-3 space group. Y(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 Y(1) atoms. In the second Pd site, Pd(2) is bonded in a distorted octahedral geometry to six equivalent Y(1) atoms. In the third Pd site, Pd(3) is bonded in a 10-coordinate geometry to seven equivalent Y(1) and three equivalent Pd(3) atoms.
Y3Pd4 crystallizes in the trigonal R-3 space group. Y(1) is bonded in a 9-coordinate geometry to one Pd(1), one Pd(2), and seven equivalent Pd(3) atoms. The Y(1)-Pd(1) bond length is 2.89 Å. The Y(1)-Pd(2) bond length is 2.96 Å. There are a spread of Y(1)-Pd(3) bond distances ranging from 2.85-3.33 Å. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 6-coordinate geometry to six equivalent Y(1) atoms. In the second Pd site, Pd(2) is bonded in a distorted octahedral geometry to six equivalent Y(1) atoms. In the third Pd site, Pd(3) is bonded in a 10-coordinate geometry to seven equivalent Y(1) and three equivalent Pd(3) atoms. There is one shorter (2.91 Å) and two longer (2.97 Å) Pd(3)-Pd(3) bond lengths.
