Abstract
Abstract Four 2-methylquinoline derived supramolecular complexes [2-methylquinoline: (2,4,6-trinitrophenol) [(HL) + · (pic − ), pic − = picrate, L = 2-methylquinoline] ( 1 ), 2-methylquinoline: (5-nitrosalicylic acid) [(HL) + · (5-nsa − ), 5-nsa − = 5-nitrosalicylate] ( 2 ), 2-methylquinoline: (5-sulfosalicylic acid): H 2 O [(HL) + · (5-ssa − ). H 2 O, 5-ssa − = 5-sulfosalicylate] ( 3 ), and 2-methylquinoline: (trimesic acid) [(L)⋯(Tma), Tma = trimesic acid] ( 4 ) were synthesized and structurally characterized by X-ray crystallography. All supramolecular architectures of 1–4 involve extensive classical hydrogen bonds as well as other noncovalent interactions. The results presented herein indicate that the strength and directionality of the N H⋯O, O H⋯N, and O H⋯O hydrogen bonds (ionic or neutral) between acidic components and 2-methylquinoline are sufficient to bring about the formation of binary organic acid–base adducts. The role of weak and strong noncovalent interactions in the crystal packing is ascertained. These weak interactions combined, the complexes 1–4 displayed 2D–3D framework structure.
