The main goal of this work was to report the synthesis, characterization, and cytotoxicity study a novel copper(II)-sunitinib complex, CuSun. It has been synthesized characterized in solid state solution by different methods (such as DFT, FTIR, Raman, UV-vis, EPR, NMR, etc.). solid-state molecular structure trichlorosunitinibcopper(II), where sunitinib: N-[2-(diethylamino)ethyl]-5-[(Z)-(5-fluor...
