- Abstract
The thermal properties of dimethylgold(III) carboxylates of general formula [(CH3)2Au(OOCR)]2 ( R=methyl ( 1), tert-buthyl ( 2), trifluoromethyl ( 3), or phenyl ( 4)) in solid state have been investigated by the thermogravimetric analysis. The temperature dependences of saturated vapour pressure of complexes have been studied by the Knudsen effusion method with mass spectrometric indication. The thermodynamic parameters Δsub H T 0 and Δsub S T 0 of the sublimation processes have been calculated. Thermal decomposition of the vapour of complexes 1 and 2 has been studied by means of high temperature mass spectrometry in vacuum, and by-products of decomposition have been determined.
