Two novel binuclear Mn(II) metal-organic coordination complexes [Mn2(TBZ)2(CDC)(C2O4)]n (1), {[Mn2(TBZ)2(BDC)(0.5)(BTC)(H2O)2]·ET}n (2), (where TBZ = thiabendazole, H2CDC = trans-1,4-cyclohexanedicarboxylic acid, H2C2O4 = oxalic acid, H3BTC = 1,3,5-benzenetricarboxylic acid, ET = ethanol, H2BDC = 1,4-benzenedicarboxylate) have been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, electrochemical analysis and single crystal X-ray diffraction. The X-ray structure analysis reveals that 1 is s two-dimensional layer and 2 is s one-dimensional chain. In complex 1, it reveals 2-D layers composed of multi-(bidentate) bridging ligands (CDC and C2O4), and in 2, the coordinated BTC ligands adopt a monodentate mode and with BDC ligands adopt alternately chelating Mn1 and Mn2 bridges into 1-D chains. The 3-D structures of the two complexes are stabilized by π-π stacking interactions and hydrogen bonds.
两个新型双核 Mn(II) 金属有机配位配合物 [Mn2(TBZ)2(CDC)(C2O4)]n（1），{[Mn2(TBZ)2(BDC)(0.5)(BTC)(H2O)2]·ET}n（2），（其中 TBZ = 噻苯咪唑，H2CDC = 反式-1,4-环己烷二甲酸，H2C2O4 = 草酸，H3BTC = 1,3,5-苯三甲酸，ET = 乙醇，H2BDC = 1,4-苯二甲酸）已通过水热合成法合成，并通过元素分析、红外光谱、热重分析、电化学分析和单晶 X 射线衍射进行了表征。X 射线结构分析表明，1 是二维层，2 是一维链。在配合物 1 中，它揭示了由多（双齿）桥联配体（CDC 和 C2O4）组成的 2-D 层，而在 2 中，配位的 BTC 配体采用单齿模式，BDC 配体采用交替螯合 Mn1 和 Mn2 桥形成 1-D 链。两种配合物的 3-D 结构通过π-π堆积相互作用和氢键稳定。
