摘要

本文用水溶性的四硫富瓦烯(TTF)羧酸盐PropylTTFK2(1)合成了两种金属配合物Zn(L1)(Phen)2·CH3OH·2H2O(配合物3)和Cd(L1) (Phen)2 ·2CH3OH· H2O(配合物4)(L1=PropylTTF2-;Phen=1,10-phenanthroline).经元素分析对配合物的组成进行分析,并通过X射线单晶衍射解析了配合物的晶体结构,表明分子中存在明显的分子间S…S及氢键作用.同时也研究了配合物的紫外、荧光和电化学性质,滴定实验显示两种配合物均是很好的TCNQ电子接受体.%In this paper,two mononuclear coordination complexes Zn(L1) (Phen)2 ·CH3OH·2H2O (3) and Cd(L1) (Phen) 2· 2CH3 OH· H2O (4),(L1 =PropylTTF2-;Phen =1,10-phenanthroline) derived from a watersoluble TTF-dicarboxylate salt PropylTTFK2 (1) (PropylTTFK2 =Propylenedithio-4',5'-tetrathiafulavalene-4,5-dicarboxylate dipotassium salt) were prepared.Their structures were characterized by elemental analysis.And the crystal structures of the complex 3 and 4 were analyzed by X-ray single crystal diffraction.Noticeable inter molecular S...S or/and H-bonding interactions have been found in 3 and 4,resulting in the formation of 1D chain.All of them have been characterized by UV-Vis,fluorescence and electrochemistry.The titration of TCNQ shows these complexes can form classical electron-acceptor salt with TCNQ.
