摘　　要：Three small organic molecular co-crystal compounds （C3N6H6）·（C6H10O4）·H2O（I）, C3HsN2O（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（CEO4）（HEO）E]＇C6HllNO2（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.Three small organic molecular co-crystal compounds （C3N6H6）·（C6H10O4）·H2O（I）, C3HsN2O（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（CEO4）（HEO）E]＇C6HllNO2（2） were synthesized by hydrothermal reaction.
