摘 要:近年来,对无机碘(Ⅰ2)及其相关化合物的溶液和晶态超分子结构的研究十分活跃,但对碘基取代的芳香羧酸超分子化学研究,特别是其结构组装及性能的研究报道相对较少。芳香碘基是甲状腺素的重要功能基团,通过共价键被固定于芳环上,兼备超分子组装要求的刚性和稳定性,并仍具备碘的结构环境适应性和结合模式多样性等特点。A manganese coordination polymer, [Mn(C7H2I3O2)2(CH3OH)2]n was synthesized and characterized by the element analysis, IR, TG and single crystal X-ray diffraction structure analysis. The title complex crystallizes in monoclinic system with space group P21/c, a=0.461 66(9) nm, b=1.716 6(3) nm, c=1.647 5(3) nm,β=91.84(3)°, and V=1.305 2(4) nm^3, Z=2, R=0.026 2, wR=0.063 4. Each manganese(Ⅱ) ion exists in an octahedral geometry with four O atoms from three different triiodobenzoate groups and two O atoms from two methanol molecules. Two adjacent manganese (Ⅱ) atoms are bridged by two triiodobenzoate groups in bis-monodentate mode, constructing a onedimensional chain structure along a axis, with the adjacent Mn … Mn distance being 0.461 7(5) nm. Moreover, the weak interactions between the iodine atoms lead to a three-dimensional supramolecular network.
