The kinetics of sublimation of bis(2,2,6,6-tetramethyl-3,5-heptanedionato)copper(II), [Cu(tmhd)(2)] was studied by non-isothermal and isothermal thermogravimetric (TG) methods. The non-isothermal sublimation activation energy values determined following the procedures of Friedman, Kissinger, and Flynn-Wall methods yielded 93 +/- 5, 67 +/- 2, and 73 +/- 4 kJ mol(-1). respectively and the isothermal sublimation activation energy was found to be 97 +/- 3 kJ mol(-1) over the temperature range of 375-435 K. The dynamic TG run proved the complex to be completely volatile and the equilibrium vapor pressure (p(e))T of the complex over the temperature range of 375-435 K determined by a TG-based transpiration technique, yielded a value of 96 +/- 2 kJ mol(-1) for its standard enthalpy of sublimation (Delta H-sub degrees).
