Binuclear macrocyclic metal complexes represent an important and integral class of organic compounds which are well recognised for their multifaceted biological properties and medicinal relevance. They are no doubt the transition metal complexes which have opened new vistas of research in present era of chemistry. Related studies to them would be of immense importance to synthetic chemist, medicinal scientists as well as in pharmaceutical industry. For the same, copper soaps (derived from common fatty acids) were complexed with nitrogen and sulphur donor ligand (special reference to substituted phenylthiouea). These novel complexes were characterised by IR, NMR, ESR spectral and elemental studies. TGA analysis was studied in detail. Thermogravimetric analysis is a thermal analysis technique which measures the amount of rate of change in weight of a material as a function of temperature or time in controlled atmosphere. TGA measurements are used primarily to determine composition of soap and to predict their thermal stability up to elevated temperature.
