Abstract: Mixed ligand complexes of copper (II) with Thiosemi carbazones of acetophenone /benzophenone /benzaldehyde/ vanillin and chloroethanol as a second ligand are reported. The complexes are characterized by Elemental and thermal analyses, IR, UV-visible, EPRspectralstudies, and magnetic susceptibility studies.Antibacterial, Antifungal activities were carried out on these complexesagainst the bacteria, E.coli, Salmonella typhi, Bacillus subtilis, staphylococcus auerus, Pseudomonas aeruginosa and against the fungi, candida albicans, Trichodermaviridi and Aspergillus niger.The invitro cytotoxicity of the complexes against HT 29 colon cancer cells showed excellent activity with very low IC 50 values together with significantly higher selectivity index.
