Supramolecular Salts

Mixtures of 4-carboxypyridinium perchlorate or 4-carboxypyridinium tetrafluoroborate and 18-crown-6 (1,4,7,10,13,16-hexaoxacyclooctadecane) in ethanol and water solution yielded the title supramolecular salts, C6H6NO2+·ClO4−·C12H24O6·2H2O and C6H6NO2+·BF4−·C12H24O6·2H2O. Based on their similar crystal symmetries, unit cells and supramolecular assemblies, the salts are essentially isostructural. The asymmetric unit in each structure includes one protonated isonicotinic acid cation and one crown ether molecule, which together give a [(C6H6NO2)(18-crown-6)]+supramolecular cation. N—H...O hydrogen bonds between the protonated N atoms and a single O atom of each crown ether result in the 4-carboxypyridinium cations `perching' on the 18-crown-6 molecules. Further hydrogen-bonding interactions involving the supramolecular cation and both water molecules form a one-dimensional zigzag chain that propagates along the crystallographiccdirection. O—H...O or O—H...F hydrogen bonds between one of the water molecules and the anions fix the anion positions as pendant upon this chain, without further increasing the dimensionality of the supramolecular network.

Three binary and one ternary charge-transfer complexes have been made using 1,3,5-trinitrobenzene, viz. 1,3,5-trinitrobenzene–2-acetylnaphthalene (1/1), C6H3N3O6·C12H10O, (I), 1,3,5-trinitrobenzene–9-bromoanthracene (1/1), C14H9Br·C6H3N3O6, (II), 1,3,5-trinitrobenzene–methyl red (1/1), C15H15N3O2·C6H3N3O6, (III) (systematic name for methyl red: 2-{(E)-[4-(dimethylamino)phenyl]diazenyl}benzoic acid), and 1,3,5-trinitrobenzene–1-naphthoic acid–2-amino-5-nitropyridine (1/1/1), C6H3N3O6·C11H8O2·C5H5N3O2, (IV). All charge-transfer complexes show alternating donor and acceptor stacks, which have weak C—H...O hydrogen bonds perpendicular to the stacking axis. In addition, complex (IV) is a crystal engineering attempt to modify the packing of the stacks by inserting a third molecule into the structure. This third molecule is stabilized by strong hydrogen bonds between the carboxylic acid group of the donor molecule and the pyridine acceptor molecule.
