Polymer complexes. LXVIII. Spectroscopic studies of supramolecular copper (II) polymeric complexes of biologically active monomer derived from novel sulfa drug

The novel ligand N-[4-(5-methylisoxazol-3-ylsulfamoyl) phenyl] acrylamide (HL) 
was prepared via amidation of 4-amino-N-(5-methylisoxazol-3-yl) benzenesulfonamide with 
acryloyl chloride in benzene as solvent. Polymeric complexes with HL were prepared and 
characterized using elemental analysis, spectral studies (infrared, mass, UV–visible and 
electron paramagnetic resonance), powder X-ray diffraction, thermal analysis, molar 
conductivity and magnetic susceptibility. Infrared spectral studies reveal that HL behaves as 
a neutral bidentate ligand. Powder X-ray diffraction patterns of HL and polymer complexes 
show many diffraction peaks which indicate polycrystalline phases. Based on magnetic 
moment and solid reflectance measurements, the polymer complexes have square planar 
and octahedral geometries.
