The new b-diketones with a methoxy group of the type (R1R2)C(O -CH3)COCH2COR 3 and their barium complexes have been synthesized. The barium fldiketonates obtained were identified and characterized by elemental, IR and Raman spectroscopic analyses, TG, DTG and DTA analyses carried out in vacuo and at atmospheric pressure have allowed the determination of the relative volatility and thermal stability of these barium complexes. The influence of the methoxy group, by type of substituent in the ligand, has been investigated by mass spectrometry. It has been found that the introduction of bulky end substituents into the ligand does not reduce the maximal oligomerization degree of barium b-diketonates in the gas phase.
