Synthesis, Structures and Properties of Two Metal-Organic Coordination Polymers Derived from Manganese(ΙΙ), Thiabendazole and Polydentate Carboxylic Acids

Two novel binuclear Mn(II) metal-organic coordination complexes [Mn(2)(TBZ)(2)(CDC)(C(2)O(4))](n) (1), {[Mn(2)(TBZ)(2)(BDC)(0.5)(BTC)(H(2)O)(2)]·ET}(n) (2), (where TBZ = thiabendazole, H(2)CDC = trans-1,4-cyclohexanedicarboxylic acid, H(2)C(2)O(4) = oxalic acid, H(3)BTC = 1,3,5-benzenetricarboxylic acid, ET = ethanol, H(2)BDC = 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 C(2)O(4)), 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.
