PuCrPd2 crystallizes in the trigonal R3m space group. Pu(1) is bonded in a 10-coordinate geometry to four equivalent Cr(1), three equivalent Pd(1), and three equivalent Pd(2) atoms. There is one shorter (2.64 Å) and three longer (2.86 Å) Pu(1)-Cr(1) bond lengths. All Pu(1)-Pd(1) bond lengths are 2.70 Å. All Pu(1)-Pd(2) bond lengths are 2.70 Å. Cr(1) is bonded in a distorted single-bond geometry to four equivalent Pu(1), one Pd(1), and three equivalent Pd(2) atoms. The Cr(1)-Pd(1) bond length is 1.65 Å. All Cr(1)-Pd(2) bond lengths are 2.70 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a single-bond geometry to three equivalent Pu(1), one Cr(1), and one Pd(2) atom. The Pd(1)-Pd(2) bond length is 2.64 Å. In the second Pd site, Pd(2) is bonded in a 7-coordinate geometry to three equivalent Pu(1), three equivalent Cr(1), and one Pd(1) atom.
