Abstract
Chromium, molybdenum and ruthenium complexes of chloranilic acid (H2CA) were investigated by the thermogravimetric (TG) technique. The TG plot of Cr(H2CA)3 showed three decompositions in the temperature range 336-802°K. On the other hand, the TG plot of MoO3(HCA) complex displayed successive weight losses in four steps covering the temperature range 350-1278°K. The thermal decomposition of the cluster compound Ru3(CO)10(μ-H)(HCA) occurred in three steps within the decomposition temperature range 302-764°K. Calculation of the reaction order of decompositions of the three complexes revealed that they follow first-order kinetics. The thermodynamic parameters for the different decomposition steps of the complexes were also determined from their DTG plots. (C) 2000 Elsevier Science B.V.
