“…The 1 H NMR spectra are recorded at room temperature on Brucker 250 WM (250 MHz) spectrometer in DMSOd 6 . The 13 C NMR spectra are recorded also at room temperature on Brucker 250 WM (62.9 MHz) spectrometer in DMSO-d 6 . The chemical shifts are in ppm, downfield from TMS.…”

“…Their complexation ability in respect to different metal ions has been studied and discussed widely in a considerable number of investigations [5][6][7][8][9]. It has been found that the binding of a metal to the coumarin moiety retains or even enhances its biological activity [10][11][12].…”

“…The nature of the metal-ligand bonding is confirmed by the newly formed bands at ~ 550 cm -1 and ~ 470 cm -1 in the spectra of complexes( Fig. 2-5), which is tentatively assigned to Cu-O and Cu-N vibrations [9][10][11] . …”

“…These bands at 474-478 cm -1 region observed in all complexes could be tentatively assigned to ṽ(M-O) vibrations. [24,29,30] In the other band, acetate anion bands for complexes were observed at 1440-1454 cm -1 which indicated to the mentioned anion. [31]…”
