The isostructural salts benzene-1,2-diaminium bis(pyridine-2-carboxylate), 0.5C6H10N2 2+·C6H4NO2 −, (1), and 4,5-dimethylbenzene-1,2-diaminium bis(pyridine-2-carboxylate), 0.5C8H14N2 2+·C6H4NO2 −, (2), and the 1:2 benzene-1,2-diamine–benzoic acid cocrystal, 0.5C6H8N2·C7H6O2, (3), are reported. All of the compounds exhibit extensive N—H...O hydrogen bonding that results in interconnected rings. O—H...N hydrogen bonding is observed in (3). Additional π–π and C—H...π interactions are found in each compound. Hirshfeld and fingerprint plot analyses reveal the primary intermolecular interactions and density functional theory was used to calculate their strengths. Salt formation by (1) and (2), and cocrystallization by (3) are rationalized by examining pK a differences. The R 2 2(9) hydrogen-bonding motif is common to each of these structures.

Molecular structures of 4-(((4-methoxyphenyl)amino)methyl)-N,N-dimethylaniline and 2-methoxy-5-((phenylamino)methyl)phenol synthesized via Schiff bases reduction route are reported. The compounds consist of asymmetric units of C16H20N2O (1) and C14H15NO2 (2) in orthorhombic and monoclinic crystal systems, respectively. Compound 1 consist of intermolecular C11—H11···N2 hydrogen bonding with C11···N21 = 3.463(4) Å. The hydroxyl group in 2 is also involved in intermolecular O2—H2···O2 and O2—H2···O21 hydrogen bonding with O2···O11 = 2.8885(15) Å and O1···O21 = 2.9277(5) Å. The molecular structures of the compounds are stabilized by secondary intermolecular interactions of C1—H1B···O11 and C5—H···(C41, C51, C61, C71) for 1 and H···C, C—H···O and N—H···C for 2. The reported compounds are important starting material for the synthesis of many compounds such as azo dyes and dithiocarbamate.

The following Schiff bases have been synthesized: (1) 4-(2-chlorobenzylidene)amino benzoic acid JP1, (2) 4 (furan-2-ylmethylene)amino benzoic acid JP2, (3) 4-[(3-phenylallylidene)amino]benzoic acid JP3, (4) 4 (2-hydroxybenzylidene)amino benzoic acid JP4, (5) 4 (4-hydroxy-3-methoxybenzylidene)amino benzoic acid JP5 and (6) 4 (3-nitrobenzylidene)amino benzoic acid JP6. They were screened as potential antibacterial agents against a number of medically important bacterial strains. The antibacterial activity was studied against A. faecalis ATCC 8750, E. aerogenes ATCC 13048, E. coli ATCC 25922, K. pneumoniae NCIM 2719 S. aureus ATCC 25923, P. vulgaris NCIM 8313, P. aeruginosa ATCC 27853 and S. typhimurium ATCC 23564. The antibacterial activity was evaluated using the Agar Ditch method. The solvents used were 1,4-dioxane and dimethyl sulfoxide. Different effects of the compounds were found in the bacterial strains in vestigated and the solvents used, suggesting, once again, that the antibacterial activity is dependent on the molecular structure of the compound, the solvent used and the bacterial strain under consideration. In the present work, 1,4-dioxane proved to be a good solvent in inhibiting the above stated bacterial strains.
