摘要：

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 similar to 10(-2) mm Hg have been determined. Experimental evidence is presented that the complexes are similar in volatility. (C) 2009 Elsevier B. V. All rights reserved.
