Abstract

In this study, amidation of aliphatic amine with acryloyl chloride in the dry benzene as solvent has been prepared. Moreover, the polymer complexes have been prepared. All compounds have been characterized by the analytical, spectroscopic ( IR, UV, NMR, ESR) and thermal methods. Addition, the magnetic susceptibility and molar conductance measurements have been made. Acryloylhydrazin (AH) has been shown to behave as a bidentate logand via its nitrogen (of the NH; of hydrazine group) and C-O/ C=0 (of the acryloyl group) in polymer complexes, all of which exhibit supramolecular architectures assembled through weak interaction including hydrogen bonding and 1- 1 stacking The magnetic and spectral data indicate a square planar geometry for Cu²⁺ complex and an octahedral geometry for Co(II) and UO₂ (II). The ESR spectral data of the Cu(II) complexes showed that the metal-ligand bonds have considerable covalent character. The thermal stability was investigated using thermogravimetric analysis. The results showed that the polymer complexes are more stable than the homopolymer.
