Synthesis and Characterization of Two Isomers of Two-dimensional Networks Compound

The bright-blue crystals were obtained by reacting copper ( II ) perchloride with 4,5-diazafluorene-9-one (dafo) and o-phthalic acid and the glaucous crystals were obtained by reacting copper( II ) perchloride with dafo and benzoic acid. Their structures were determined by single crystal X-ray diffraction. Their crystal structures indicate that the two compounds are isomeric compounds with empirical formulas C-22H-16C-uCuN-4O-12. The two compounds as supramolecular compounds, have two-dimensional network structures formed through hydrogen bonds. In addition, the two compounds were characterized by elemental, IR spectra and thermal analyses
