## Abstract 18‐Crown[6] ether has been used to prepare a new class of organic–inorganic complexes of general formula 18‐crown[6]⋅M[HSO~4~]~__n__~ (where M = NH~4~^+^, K^+^, Sr^2+^ and __n__ = 1, 2) by reacting directly in solution or in the solid state the crown ether 18‐crown[6] with inorganic sal
