Volatile compounds of iridium(I): (acetylacetonato)(1,5-cyclooctadiene)iridium(I) Ir(acac)(cod), (methylcyclopentadienyl)
(1,5-cyclooctadiene)iridium(I) Ir(Cp’)(cod), (pentamethylcyclopentadienyl)(dicarbonyl) iridium(I) Ir(Cp*)(CO)2 and (acetylacetonato)(dicarbonyl)iridium(I) Ir(acac)(CO)2 were synthesized and identified by means of element analysis, NMR-spectroscopy, mass spectrometry.
Thermal properties in solid phase for synthesized iridium(I) complexes were studied by means of thermogravimetric analysis
in inert atmosphere (He). By effusion Knudsen method with mass spectrometric registration of gas phase composition the temperature
dependencies of saturated vapor pressure were measured for iridium(I) compounds and the thermodynamic characteristics of vaporization
processes enthalpy ΔHT* and entropy ΔST0 were determined. The energy of intermolecular interaction in the crystals of complexes was calculated.
