- Abstract
The crystal structures of the proton-transfer salts of 6-hydroxyquinoline with 3,5-dinitrobenzoic acid ( 1) and 4-nitrobenzoic acid ( 2) have been determined at room temperature. Their comparative structural features and hydrogen-bonding patterns are described here. Compound 1 crystallizes in the monoclinic P2/ c space group, while 2 in the triclinic P−1 space group. Unit cell dimensions and contents are: a = 7.6956(15), b = 26.075(5), c = 7.7233(15) Å, β = 95.96(3)° for 1; a = 7.7325(15), b = 8.5939(17), c = 12.394(3) Å, β = 77.63(3)° for 2. Supramolecular architectures are formed by intermolecular hydrogen bonds in the proton-transfer process. The supramolecular structures are stabilized by N-H···O, O-H···O and C-H···O hydrogen bonds between the two components. Extensive hydrogen-bonding interactions give two-dimensional network structures. In addition, π-π stacking interactions exist in the salt 1 due to the aromatic rings.
