In the present study, an electrochemical technique based on the release of Cu2+ ions from a Cu anode in the presence of unsaturated fatty acids with different alkyl chain lengths has been used to synthesize Cu(ii) carboxylates. The fatty acids used in this study are lauric acid (C12:0) and stearic acid (C18:0). Optimum electrolysis conditions for the synthesis of Cu(ii) laurate (CuLa2) and Cu(ii) stearate (CuSt2) have been determined to maximize percentage yield and minimize energy consumption and loss of the Cu anode. We observe that both compounds (99.21%) are produced with lower energy consumption (～21.01 W h L-1) and anode loss (～0.57 mg L-1) by using the same optimum conditions of 10 V of applied voltage for 4 hours of electrolysis time in 0.1 M CH3COONH4 electrolyte solution. The cytotoxicity study on selected tumor cells (A549 and HeLa) shows that the synthesized compounds have moderate cytotoxic effects with IC50 in the range from 19.50 to 44.67 μM. CuLa2 with C12 alkyl chains provides better cytotoxicity effect on the selected tumor cells due to lower IC50 than CuSt2 with C18 alkyl chains. This shows that the length of alkyl chain also affects the compound toxicity towards selected tumor cells.

FTIR spectra of copper nonanoate, decanoate, undecanoate and dodecanoate are recorded every 5 K from room temperature to 390 K.Changes detected in the infrared spectra when heating the sample allow the heat absorptions observed in some of these samples prior to the transition to the mesophase to be explained as due to conformational changes taking place in the alkyl chain next to the carboxylate group.Low frequency infrared and Raman spectra are consistent with a D4h geometry for the ionic core where the copper ions are located.Moreover, the study of the low frequency region at the temperature of the mesophase permit the detection of rearrangement around the central core in the transition from the crystal to the mesophase.
