| Abstract | ||
| This work involves the preparation and investigation of new coordination complexes of Cu(II) with the ligands thiolactic acid (L1) and thioglycolic acid (L2). The analysis of the purified products with IR, UV and magnetic measurements shows square-planer environment of the complexes having the following formula: [M(L1)2] and [M(L2)2], where M is the transition metal (Cu). The prepared complexes where converted to macromolecules through the addition of ethylene diamine (en) and diethylene triamine (dien). The new products show the hexa-coordination configuration when investigated by using the prementioned techniques. The limiting viscosity measurements show that the new products possesses high molecular weights when compared with the original complexes. This observation reveals that the terminal and intermediate amine groups are playing an important role in connecting neighbour molecules or ions and converting them to macromolecules. Thermal stability thermograms show the high stability of the new complexes if compared with the original once. Also, the stability increased directly with the amount of the amine added. | ||
