THEORETICAL AM1 AND PM3-QUANTUM CHEMICAL CALCULATION FOR SOME SCHIFF BASES

Schiff bases are used widely for various complexation reactions with various metal ions. these can be obtained easily from various corbonyl containing compounds and amino compounds by a simple condensation reaction proceeding by loss of water molecule. schiff bases are stable compounds and can beused as ligands for synthesis of various complexes. the electronic structure of some of these schiff bases can be done by am1 and pm3 semi-empirical quantum chemical calculations. such studies act as aid tolocate and confirm, the co-ordination site of these bases, which bind to various metal ions.
