Cs Cs Pu Zn
Cs2PuZn crystallizes in the trigonal R3m space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 7-coordinate geometry to one Cs(2), three equivalent Pu(1), and three equivalent Zn(1) atoms. The Cs(1)-Cs(2) bond length is 2.28 Å. All Cs(1)-Pu(1) bond lengths are 4.57 Å. All Cs(1)-Zn(1) bond lengths are 4.21 Å. In the second Cs site, Cs(2) is bonded to one Cs(1) and three equivalent Pu(1) atoms to form distorted corner-sharing CsCsPu3 tetrahedra. All Cs(2)-Pu(1) bond lengths are 4.57 Å. Pu(1) is bonded in a single-bond geometry to three equivalent Cs(1), three equivalent Cs(2), and one Zn(1) atom. The Pu(1)-Zn(1) bond length is 2.28 Å. Zn(1) is bonded in a single-bond geometry to three equivalent Cs(1) and one Pu(1) atom.
