Synthesis, biological and molecular modeling studies of macrocyclic complexes of trivalent metal ions

The macrocyclic complexes of biological importance with power transition metals are synthesized by template methodology leading to the formation of the complex [MLX] X2; where L is macrocyclic ligand derived from 3,4-diaminotoluene, 2,4-thiazolidinedione, M=Cr (III) and Fe(III) X is Cl-, CH3COO- or NO3_.Characterisation of these complexes are through with the assistance of elemental analyses(CHN), molar conductance measurements, magnetic susceptiblities measurements and infrared spectral studies. Molecular modelling was done by using Avagadro 1.01 progarm and optimised geometry in which energy calculations of macrocyclic complexes were determined. Synthesised complexes were also screened for their biological activities such as antimicrobial,antifungal and antioxidant activities.
