摘　　要：本文合成了通式为［Ｎａ（ＤＢ１８Ｃ６）Ｘｎ］２Ｍ６Ｏ１９Ｙ（Ｍ＝Ｗ和Ｍｏ，Ｘ＝Ｈ２Ｏ和ＣＨ３ＯＨ，ｎ＝１和２，Ｙ＝（ＤＢ１８Ｃ６）·（ＣＨ３ＯＨ）和（ＤＭＦ）２·（ＣＨ３ＯＨ）３）的四种冠醚多酸超分子配合物，进行了红外、核磁和元素分析等表征，用四圆衍射测定了晶体结构，并对配合物的热分解过程进行了研究．结果表明，实验条件的变化，可导致相同的反应物形成键型不同、结构不同的产物．our new supermolecular complexes of [Na(DB18C6)X n] 2M 6O19Y where M=W and Mo, X=H 2O and CH 3OH, n =1 and 2, Y=(DB18C6)·(CH 3OH) and (DMF) 2·(CH 3OH) 3 were synthesized. The structure were characterized by IR、1HNMR and Elemental Analysis and determined by fourcircle X Ray diffractometer. Their thermal properties were inversitigated by TG and DTA. It was found that the products with different bond and structure can be obtained by the same reacting substances in different experimental processes.
