摘要：

The mononuclear complexes of Zn(II), Cd(II) and Hg(II), [Zn(phen-dione) Cl-2], [Cd(phendione)Cl-2] and [Hg(phen-dione)Cl-2], where phen-dione 1,10-phenanthroline-5,6-dione, have been synthesized and characterized by elemental analysis and IR, (HNMR)-H-1 and electronic absorption spectroscopies. The v(C=O) of coordinated phen- dione ligands in these complexes shows that the phen- dione is not coordinated to metal ion from its C = O sites. Electronic spectra of the complexes show two absorption bands for intraligand transitions. These absorption bands show dependence on the dielectric constant of solvents. These complexes exhibit an intense fluorescence band around 545 nm in DMSO when the excitation wavelengths are 200 nm at room temperature.
