以2,3,6,7-四(2’-氰乙硫基)四硫富瓦烯为桥配体的前驱物, 合成了标题配合物μ-(ttftt)-[M(phen)]2 (M=MnII, FeII, CoII, NiII, CuII, ZnII). 配合物的结构和性质经由元素分析、核磁共振波谱、红外光谱、紫外-可见光谱、荧光光谱、摩尔电导率和量子化学计算表征, 研究了电氧化还原和对Li/SOCl2电池的催化特性. 发现铁和钴配合物具有较高的催化活性且有利于电池的大电流和低温放电, 在25 ℃和电流密度25 mA/cm2条件下铁配合物使电池的电压和容量分别提高了133 mV和218 mAh.

The title complexes μ-(ttftt)-[M(phen)]2 (M=MnII, FeII, CoII, NiII, CuII, ZnII) were synthesized by using 2,3,6,7-tetrakis(2’-cyanoethylthio)tetrathiafulvalene tetrathiolate as the precursor of bridge ligand. The structure and properties were characterized by using elemental analysis, NMR, IR, UV-Vis spectra, florescence spectra, mole electrical conductivities and quantum chemistry theoretical calculation. The electrochemical oxy-reduction and electrocatalysis for the Li/SOCl2 cell was studied, discovering that the increases of voltage and capacity of the cell containing the μ-(ttftt)-[Fe(phen)]2 are 133 mV and 218 mAh at 25 ℃ by current density 25 mA/cm2.

Key words: tetrathiafulvalene tetrathiolate, metal 1,10-phenanthroline, synthesis, electrocatalysis, quantum chemistry calculation
