Novel polymeric complexes with a potentially bidentate ligand N-[β-(ethylamino)] 
acrylamide (EA), formed by amidation of 1, 2-diaminoethane with acryloyl chloride were 
synthesized and characterized on the basis of elemental analyses, IR, 1 H NMR, UV–Vis, 
magnetic susceptibility measurements, ESR, molar conductance and thermal analysis. 
Molecular docking was used to predict the binding between EA ligand (keto and enol forms) 
and the receptor of prostate cancer mutant 2q7k-hormone and the receptor of breast
