SPECTROSCOPIC PROPERTIES OF BIS(IMIDAZOL)COPPER(II)DIACETATE

Electronic and vibrational spectra of bis(imidazol)copper(II)diacetate were investigated in order to obtain a wider insight into the structural properties of this interesting complex compound, which presents high cytotoxic activity. Electronic transitions were investigated by reflectance measurements of the solid and by absorption, using aqueous and methanolic solutions. IR spectra could be interpreted on the basis of the characteristic ligand vibrations. Some information could also be obtained for the Cu-N and Cu-O vibrations. For comparative purposes, the IR spectrum of Cu(imidazol)4I2 was also recorded and analyzed.
