Synthesis and Characterization of Coordination polymers of Bis-(mercaptoacatamido) - Butanedioane Dihydrazone
A. D. Bansod
Abstract: Coordination polymers of Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and Cd (II) with bis-bidentate ligand delivered from mercaptoacetic acid and 2,3 butanedione dihydrazone have been prepared. All polychelates are coloured, amorphous solid insoluble in water and common organic solvents and characterized with the aid of analytical, magnetic, spectral and thermal studies. The Mn(II),Co(II) and Ni(II) polychelates are of a six co-ordinated octahedral structure, where as Zn(II) and Cd(II) polychelates are found to be four co-ordinated while Cu(II) exhibit square planer structure respectively. Elemental analysis indicators a metal: ligand ratio 1:1 by using graphical Freeman?Carrol method various thermodynamics parameters have also been evaluated. Thermal stability of the complexes have been tested for their antibacterial activity against the bacteria E coli, Bacillus sp, stappylocous and Pseudomonus sp. The solid state conductivity of ligand and complexes were also measured in their compressed pettet from in the temperature range 310-450 K and all complexes were are found to be semiconducting in behaviour.
