Abstract
Cation arrangement in some complex fluoride structures with U4+, Th4+, and Zr4+ differing in composition, symmetry, and unit cell parameters is analyzed. In all structures investigated, we have isolated (using the CAS-PAN technique) a common structural fragment: planar close-pack ed cation nets (3(3)4(2) + 3(6)) characteristic of the high-symmetry b eta-K2UF6 structure chosen as the standard. The whole set of close-fil led cation planes is described. A cation-anion fragment - columns or r ibbons of high-valent cation polyhedra - has been isolated which deter mines the main structural peculiarities.
