College of Education, University of Samarra discussed a Ph.D. thesis on  preparing, spectral diagnosis, and thermal study of the complexes of ions of some metallic elements with new cyclic ligands.

The thesis aimed at testing the susceptibility of some metal complexes [Cu2(L1)Cl4] and [Co2(L1)Cl4] as antibiotics to inhibit the breast cancer cell line (7-MCF) and compare it with the cell line of normal cells (HdFn) by the postgraduate student, Mr. Mohamed Ahmed Mudhi.

The thesis reviewed that the copper complex has an effective toxic effect against the cells of the breast cancer cell line (7-MCF) higher than the cobalt complex because it kills almost half of the cancer cells and is less toxic to normal cells and less than the cobalt complex.

The thesis demonstrated that some of the prepared metallic complexes have paramagnetic properties, with measurements of the molar conductivity of the prepared complexes dissolved in DMSO at a concentration of 1 × 3-10 M and at the laboratory temperature indicating that they are of a non-electrolytic nature.
