摘要：
Coordination of the Am and Cm atoms in the crystal structures of oxygen-containing compounds was analyzed using Voronoi–Dirichlet polyhedra (VDPs). These actinides (An) form coordination polyhedra AnOn (6 ≤ n ≤ 9) of eight types. At a fixed oxidation state of An, the volume of the corresponding VDP is virtually independent of the coordination number n. Analysis of the characteristics of atomic VDPs in the An sublattices revealed compounds with binding An–An 5f interactions in the crystals. © 2018, Pleiades Publishing, Inc.
