Abstract
The alkaline-earth metal complexes [M(Pta)2(15C5)] (M = Ca, Sr, and Ba; Pta is the 1,1,1-trifluoro-5,5-dimethylhexane-2,4-dionate anion; 15C5 is 15-crown-5) were obtained from PtaH and 15C5 in toluene. The complexes were characterized by IR and 1H NMR spectra and TGA data. The structures of [Ca(Pta)2(15C5)] and [Ba(Pta)2(15C5)] were confirmed by X-ray diffraction analysis. The volatility and thermal stability decrease in the order [Ca(Pta)2(15C5)] > [Sr(Pta)2(15C5)] > [Ba(Pta)2(15C5)].
