This review gives an account of the coordination chemistry of supramolecular Schiff 
base polymer complexes. The synthesis and structures of Schiff base monomers and their 
polymer complexes were described. Spectral techniques like (IR, 1 H-NMR) and thermal 
analysis were investigated. ESR spectral data provided information about their structure on 
the basis Hamiltonian parameters and degree of covalency. The ESR data in connection 
with the structures and the nature of the bonding in these polymer complexes were .
