INTRODUCTIONSchiff bases have been used as chelating ligands in the field of co-ordination chemistry and their metal complexes are of great interest for many years It is well known that N and S atoms play a key role in the co-ordination of metals at the active sites of numerous metallobiomolecules Where M=Mn III and Mn II. The adducts have been characterized on the basis of elemental analyses molar conductance, I.R , visible spectra, magnetic susceptibility measurement and TGA. The ligands behave in dibasic tridentate manner in 5-methyl2-hydroxyacetophenon emorpholine-N-thiohydrazone and 5-chloro2-hydroxyacetophenonemorpholine-N-thiohydrazone. While5-methyl2hydroxyacetoph enoneantipyrine behaves in monobasic tridentate manner. All these compounds are paramagnetic in nature and have octahedral geometry.

The present work describes synthesis, spectral characterization, and X-ray diffraction studies of Cr(III) with “metformin,” an oral antidiabetic drug. The conductometric titration using monovariation method indicates that complex is ionic and of L2M type. Analytical data agree with the molecular formula of complex namely, [(C4H11N5)2Cr(H2O)2]2Cl. Geometry of complex assigned is octahedral, supported by IR, electronic spectra, magnetic moments,1H-NMR and mass studies, and proposed structure (I) for complex. X-ray diffraction data also supports the complex formation and symmetry of complex and various parameters like particle size, porosity, volume of unit cell, and density have been calculated. The Freeman-Carroll and Sharp-Wentworth methods have been used to calculate activation energy and thermal stability. The activation energy(Ea)calculated with the help of these methods are in agreement with each other. Thermodynamic parameters such as free energy change (ΔF) and entropy change are also determined on the basis of TG curves and by using data of the Freeman-Carroll method.
