In Rb2NaAlF6 a large and heavy Rb cation stabilizes cation and anion sublattices, promoting their maximum symmetry. In the structure of cyclic tetraphosphate, the core is formed by the cation sublattice with a noticeable deviation of P cations from its nodes. The anion arrangement ordered by pseudo-cubic and hexagonal sublattices with pseudo-symmetry features dominates in the trigonal structure of phenakite.
