【摘要】 合成了通式为（Ｃ１５Ｈ１５Ｎ２Ｏ３）ｘＲＥ（ＮＯ３）ｙ（Ｈ２Ｏ）ｚ（当ＲＥ＝Ｌａ～Ｐｒ时，ｘ＝３，ｙ＝６，ｚ＝０；ＲＥ＝Ｎｄ时，ｘ＝２，ｙ＝５，ｚ＝１；ＲＥ＝Ｓｍ～Ｌｕ，Ｙ时，ｘ＝２，ｙ＝５，ｚ＝０）的一系列１５种标题配合物．通过元素分析，ＩＲ，ＵＶ，１ＨＮＭＲ，ＴＧ－ＤＴＡ，摩尔电导和Ｘ射线粉末衍射分析等对配合物的性质进行了表征．认为可能生成包含一分子水的１１配位钕配合物的原因在于抗衡阳离子的空间效应，使其与络阴离子间的ｖａｎｄｅｒＷａａｌｓ力增强的结果更多还原

【Abstract】 The title complexes, represented by a general formula (C 15 H 15 N 2O 3) x RE(NO 3) y (H 2O) z , when RE=La～Pr, x=3, y=6, z=0; RE=Nd, x=2, y=5, z=1; RE=Sm～Lu,Y,x=2, y=5, z=0; have been synthesized by the reaction of rare earth nitrate with 2 [2 (3 nitro 4 methoxylphenyl)vinyl] 1 methylpyridinium nitrate in ethanol solution and have been characterized by the element analysis, IR, UV and 1H NMR spectra, TG DTA, molar conductance and X ray powder diffraction. The results show that the crystal form of Nd complex containing one molecule of water as a ligand is eleven coordinated and is different from the others. The reason is attributed to the stronger van der Waals force between the coordinated anion and the cation having the space effect.更多还原
