Thermogravimetric investigation of thermal decomposition of copper(II) complexes with methylpyrido[2,3-d]imidazole derivatives

Abstract

Solid-state complexes with the formulae CuLxX2-nH20, were L=2-methyl-, 5-methyl-, or 7-methylpyrido[2,3-d]imidazole, X=NO~ or Ci-, x=2 or 3, and n---1 or 2, were subjected to thermogravimetric analyses. The kinetic parameters were calculated according to the Coats-Redfern method. Reactions paths are proposed and their agreement with the data obtained from TG curves is checked.
