Abstract
A motif of the supramolecular architecture of соcrystals of 18-crown-6 and polychloropolyfluoro-1,3-phenylenediamines or partially fluorinated 1,3-phenylenediamines (1:1 stoichiometry) is infinite 1D ensembles of alternating components. Mutual coordination of molecules in the ensembles is due to the hydrogen bond between crown ether oxygen atoms and hydrogen atoms of polyfluoroarene amino groups. Parameters of the architecture of соcrystals are determined by the effect of the number and positions of substituents (chlorine and fluorine atoms) in the polyhalogenated aromatic ring.
