Abstract

A geometric and topological analysis of the crystal structure of U16Pu42-hP58 with rhombohedral cell parameters arh = 10.685 Å, α = 89.74°, V = 1219.96 Å3, and sp. group R-3m is realized using computer methods (ToposPro software package). A new two-layer nanocluster-precursor 0@8(U2Pu6)@36(U12Pu24) with an internal polyhedron of 8 atoms in the form of a hexagonal bipyramid U2Pu6 and an outer shell of 36 U12Pu24 atoms is established. The center of cluster-precursor K44 is in position 4a with point symmetry –3m. The symmetry and topological code of the processes of self-assembly of 3D structures from precursors-clusters K44 are reconstructed in the following form: primary chain → layer → framework. Spacers, which occupy positions 4b with point symmetry –3m and are double gear rings (Pu6)2 associated with two U atoms, are located in the voids of the frame K14 = U2Pu12.
