Abstract:

Three small organic molecular co-crystal compounds (C3N6H6)·(C6H10O4)·H2O(1), C3H8N2O(3) and (H4btec)2·(4,4'-bipy)(4)(H4btec=1,2,4,5-benzenetetracarboxylic acid, 4,4'-bipy=4,4'-bipyridine) and one coordination supramolecular compound [Mn(C2O4)(H2O)2]·C6H11NO2(2) were synthesized by hydrothermal reaction. They were characterized by elemental analysis, infrared(IR) spectroscopy and single crystal X-ray diffraction(XRD). Structural analyses reveal that these 2D or 3D supramolecular networks of the compounds were formed by C―H···O, N―H···O, N―H···N, O―H···O and O―H···N hydrogen bonds. Therein, the functional groups of ―COOH, ―NH2 and ―OH play important roles in constructing supramolecular architectures.

Key words: co-Crystal compound, Hydrogen bond, Hydrothermal reaction
