📓 The book in hand can furnish baseline information about transition metal complexes synthesized by the reaction of metal salts with Schiff base derived from aniline and salicylaldehyde. All these complexes soluble in DMSO have been characterized through physical techniques such as melting point and elemental analysis, it has been observed that organic ligand bound to central metal atom through the oxygen bond of hydroxyl group, the physical state of metal complexes after reaction with the ligand vary from metal to metal. The complex confirmation was made through melting point and also through elemental analysis. The IR data of the complexes provide sufficient information about the geometry of complexes. Therefore it should be in every scientific library around the country.
