  Picoline as ligand with antimony trichloride and triiodide adducts

  摘要：

  Solid adducts SbX3.L-pic (X=Cl, I and L=alpha-, beta- and gamma-picolines) were synthesized and characterized by elemental analysis, H-1 and C-13 NMR, IR spectroscopy and thermal analysis. ne infrared spectroscopy and the magnetic resonance for H-1 and C-13 nuclei of these compounds suggest that the ligands coordinate through nitrogen atom. Kinetic studies were accomplished by means of thermogravimetric data, through isothermal and non-isothermal techniques. The best adjusting models for adducts thermal decomposition were R-1 for isothermal and R-1 and R-2 for the non-isothermal methods. The energy of activation values obtained by isothermal method indicate the following orders of thermal stability for adducts: i) SbCl3.alpha-pic>SbCl3.beta-pic>SbCl3.gamma-pic and ii) SbI3.beta-pic

  to evaluate the enthalpy change of reaction: SbI 3 (cr) + L(l) = SbI 3 ·L(cr), 61.13 ± 1.75, −82.60 ± 1.55, −67.50 ± 0.97 and −74.10 ± 1.19 kJ mol −1 , respectively. Enthalpy change values for decomposition of adducts, lattice enthalpies and enthalpies of the Lewis acid–base reaction in the gas phase were calculated through appropriate thermochemical cycles. Mean Sb N bond enthalpies were estimated
