摘　　要：本文用水溶性的四硫富瓦烯(TTF)羧酸盐PropylTTFK_2(1)合成了两种金属配合物Zn(L^1)(Phen)_2·CH_3OH·2H_2O(配合物3)和Cd(L^1)(Phen)_2·2CH_3OH·H_2O(配合物4)(L^1=PropylTTF^(2-);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（ L^1）（ Phen）2·CH3OH·2H2O（ 3） and Cd（ L^1）（ Phen）2·2CH3OH·H2O（ 4）,（ L^1= PropylTTF^（2-）; Phen = 1,10-phenanthroline） derived from a watersoluble TTF-dicarboxylate salt PropylTTFK2（ 1）（ Propyl TTFK2= 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.
