Abstract: It was the purpose of this study to investigate the thermal analysis of the first transition metal series of oxalates (MC204 •XH20, M = Cr, Mn, Fe, Co, Ni, Cu, Zn) and squarates (MC404 •XH20, M = Cr, Mn, Fe, Co, Ni, Cu, Zn). It was hypothesized that there would be no difference in the end product between the decomposition of oxalate and squarate compounds. It was also hypothesized that there would be some similarities between oxalates and squarates in terms of bonding structure as well as the relationship of bond strength and size of metal radii. The attempted synthesis of the fourteen oxocarbon anion salts was successful. The synthesis of CuC204 •XH20 under N2 atmosphere was also included. The activation energy and order of reaction of each compound was computed. Three generally accepted kinetic models are used: A. W. Coates and J. P. Redfern, E. S. Freeman and B. Carroll, and Walter K. Tang. This is an initial report of the kinetic parameters for the first transition series of metal squarates.
