New chelate polymers of sebacoyl bis-p-bromo phenyl urea with Mn (II), Co (II), Ni (II), Cu (II) and Zn (II) have been synthesized. Characterisations of the ligand and its chelate polymers have been done by elemental analysis, infrared spectra, 1H NMR spectra, reflectance spectra, magnetic susceptibility measurement and thermo gravimetric analysis. The thermal stability of chelate polymers has also determined. On the basis of instrumental analysis, it has been found that the interaction between ligand and metal ion takes place through oxygen and nitrogen. Source

The coordination polymers of a new bis ligand, sebacoyl bis-p-chlorophenyl urea with Mn(II),Co(II),Ni(II),Cu(II) and Zn(II) metal ions have been synthesized and characterized by elemental analyses, spectral, magnetic and thermal studies. Various kinetic and thermodynamic parameters such as entropy change, free energy change, apparent entropy, frequency factor and order of reaction have also been evaluated and values obtained are comparable. Tentative structure for coordination complexes has been assigned on the basis of above analyses. All the coordination polymers except Cu (II) coordination polymer are found to have tetrahedral geometry and are thermally stable. © 2011 RASĀYAN. All rights reserved. Source
