Thermal degradation mechanisms and stability analysis of monoacetylferrocene complexes

A collection of coordination compounds derived from monoacetylferrocene-based hydrazones was synthesized and examined to determine their thermal behavior. The study demonstrates that modifications within the hydrazone structure and the type of coordinated 3d-metal ion significantly affect the order and energy profile of the decomposition stages. Thermal analysis using TG, DTG, and DTA indicates that each complex undergoes several temperature-dependent degradation steps associated with the ferrocene unit and its coordination surroundings. Kinetic evaluation establishes a clear stability sequence: complexes containing Cu(II) exhibit the greatest thermal stability, followed by Zn(II) and Ni(II).
