摘要

The trans-[M(18-crown-6)(C_5HO_2F_6)_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)(C_5HO_2F_6)_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.
