The trans-[M(18-crown-6)(C5HO2F6)2] (M = Ca, Sr, Ba, Pb) complexes have been synthesized and identified. The crystal structure of the Sr complex has been determined by X-ray diffraction. The basic structural unit is the mononuclear complex trans-[Sr(18-crown-6)(C5HO2F6)2]. The thermal properties of the complexes have been correlated to their structure. The melting and decomposition ranges of the Ca, Sr and Ba complexes and their sublimation temperatures at ∼10−2 mm Hg have been determined. Experimental evidence is presented that the complexes are similar in volatility.
This article was devoted to synthesis, structure determination and thermochemical properties investigation of complex compounds (18-crown-6 contained bis-hexafluoroacetylacetonates) of strontium, lead and other IIA group metals with same structure and volatility.Figure optionsDownload as PowerPoint slide
