摘要：
The complexes trans-[Pb(18-crown-6)(NO3)(2)] (I), trans-[Pb(18-crown-6)(Hfa)(2)] (II), and [Pb-2(18-crown-6)(Tfa)(4)] (III), where Hhfa is 1,1,1,5,5,5-hexafluoropentane-2,4-dione and Htfa is 1,1,1-trifluoropentane-2,4-dione, were synthesized and identified. The structures of crystals I-III were determined by X-ray diffraction, whereas the melting and decomposition of compounds II, III were studied by the differential scanning calorimetry. The temperature of preparative sublimation of complexes II, III was determined at 10(-2) mm Hg. The semiempirical structural-thermochemical approach was used to analyze the parameters of complex II vaporization.
