Several compounds with m = 2, 3, 4, and 5 in the general formula (Me 2 ′O 2 ) 2+ (Me m–1 R m O 3m+1 ) 2– were synthesized, a number of them for the first time. They possess a layer‐type crystal structure. Bi 3+ may be the only suitable ion for the Me′ sites; R may be Ga s+ , Ti 4+ , Nb 5+ , or Ta 5+ . The restrictions on the size of Me ions increases with increasing value of m . Lattice parameter data for the compounds and indexed X‐ray powder patterns for m = 5 compounds are presented.
