Adduct Formation between Zinc Oxinate and Some Heterocyclic Nitrogen Bases – A Spectrophotometric Study
Large bathochromic shifts are observed in the visible spectrum of zinc oxinate in anhydrous chloroform on the addition of heterocyclic nitrogen bases (pyridine and its methyl derivatives).These shifts as compared to those due to solvent effects alone have been attributed to adduct formation.The shifts are accompanied by a simultaneous increase in the absorbance values.From a quantitative evaluation of this data, the adduct formation constants of what proved to be 1:2 chelate-nitrogen base adducts in most cases have been determined.A monoadduct of the lowest adduct formation constant is obtained with 2,6-lutidine.The stabilities of these adducts increased in the following order: 2,6-lutidine < 2,4,6-collidine < 2,4-lutidine < 2-picoline < pyridine < 3-picoline < 4-picoline.The stabilities seem to increase in accordance with the Lewis acid-base concept and the role of steric factors has been elaborated.The adducts except that of 2,6-lutidine possess hexa-coordinated octahedral structures.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 108-47-4
