The effect of a solvent on complexation of Zn porphyrinates with pyridine

The effect of a solvent on complexation of Zn porphyrinates with pyridine Spectrophotometric titration was used to study complexation reactions of Zn 2,3,7,8,12,13,17,18-octaethylporphyrinate and Zn 5,10,15,20-tetraphenylporphyrinate with pyridine in binary solvents toluenemethanol and toluene-ethanol at different alcohol concentrations at 20°C. Capability of both porphyrinates to give complexes with pyridine in a binary solvent, i.e., toluene-monobasic alcohol, was found to decrease by more than one order of magnitude as the alcohol concentration increased from 0 to 1 mole fraction. The effect of the solvent polarity and extent of its association due to hydrogen bonds on the complexing capability of both porphyrinates was discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Coordination Chemistry Springer Journals
