A survey of known compounds which can assume K2NiF4-type structure at least over a certain P, T range was made. The cationic radius ratios rA rB of this family of compounds were found to vary over a relatively narrow range of values around 2.00, in contrast to the much wider ranges known for other important A2BX4 structure groups, e.g., β-K2SO4, thenardite, olivine, etc., providing thereby a constraint on the crystal chemical variabilities in this group of compounds. Usefulness of the simple size parameter rA(IX) rB(VI) in predicting formation of new K2NiF4-type compounds is discussed. © 1979.
