Synthesis And Spectroscopic Studies Of Tetrakis(Acetato)Copper(Ii) Dihydrate Complex.

Bull O.S, Obunwo C.C


Copper(II) tetrakis(acetato) dihydrate complex has been synthesized using standard laboratory methods involving precipitation, filtration, evaporation and  recrystallization. The synthesis was carried out in order to re-establish the chemical nature of metal complexes in their dimeric state.  Infrared spectra of ligand and complex were recorded. Atomic Absorption, Ultraviolet-Visible Spectroscopic Studies and melting points of the complex were also recorded. The colour change in the complexation of metal to the ligand was also recorded. Infrared spectral peak for the oxygen-metal (M-O) was 490 cm-1 for copper acetate. The Infrared Spectroscopic Studies showed that copper complexed with acetate ligand by the replacement of hydrogen in the OH bond of the acetate in one hand and another via a dative bond brought about by the oxygen atom in the C=O lone pair of electrons.

Key words:  Synthesis, Spectroscopy, Tetrakis(Acetato)Copper(II), Complex.
