Five copper complexes with 4,5-diazafluoren-9-one have been reported. Some of their structures are determined by single crystal X-ray diffraction. On the basis of experimentation, all the complexes were calculated by DFT-B3LYP/LANL2DZ in Gaussian-98w. By analyzing the experimental and calculated values, it can …
