Th3Pd5 crystallizes in the hexagonal P-62m space group. Th(1) is bonded in a 8-coordinate geometry to two equivalent Pd(1) and six equivalent Pd(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a trigonal planar geometry to three equivalent Th(1) and six equivalent Pd(2) atoms. In the second Pd site, Pd(2) is bonded in a 10-coordinate geometry to six equivalent Th(1) and four equivalent Pd(1) atoms.
Th3Pd5 crystallizes in the hexagonal P-62m space group. Th(1) is bonded in a 8-coordinate geometry to two equivalent Pd(1) and six equivalent Pd(2) atoms. Both Th(1)-Pd(1) bond lengths are 2.84 Å. There are four shorter (3.04 Å) and two longer (3.33 Å) Th(1)-Pd(2) bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a trigonal planar geometry to three equivalent Th(1) and six equivalent Pd(2) atoms. All Pd(1)-Pd(2) bond lengths are 3.02 Å. In the second Pd site, Pd(2) is bonded in a 10-coordinate geometry to six equivalent Th(1) and four equivalent Pd(1) atoms.
