| 摘要: 本文通过在s区金属离子(Li+，Na+，K+，Mg2+，Ca2+)存在下，2，6-吡啶二羧酸(H2pda)或2-吡啶羧酸(picH)与Mn(Ac)2·4H2O的水热合成反应，系统探讨了s区金属离子的电荷和半径对Mn(Ⅱ)配位聚合物的结构构建以及热稳定性和溶解性能的影响。合成了2个混合金属配位聚合物[Na2Mn(pda)2]n (1)和[K2Mn(pda)2]n (2)，并通过红外和X-单晶衍射进行了结构表征：1属于正交系，空间群Pnna；2属于单斜系，空间群P2/n。同时应用荧光光谱测试研究了配合物1水溶液的荧光性质。 |

| Abstract: In the presence of s-block ion(Li+, Na+, K+, Mg2+, Ca2+), the reactions of Mn(Ac)2·4H2O with H2pda (H2pda=2,6-pyridinedicarboxylic acid) or picH (picH=picolinic acid) were studied by hydrothermal synthesis. The effect of ion radius and charge of s-block on the structure, thermal stability and solubility of Mn(Ⅱ) coordination polymer was discussed systematically. Two mixed-metal coordination polymers [Na2Mn(pda)2]n (1) and [K2Mn(pda)2]n (2) have been synthesized by hydrothermal synthesis and characterized structurally by IR and single crystal X-ray diffraction. 1 crystallizes in the orthorhombic space group Pnna, 2 in monoclinic space group P2/n. The aqueous solution of complex 1 shows interesting fluorescent property caused by pda2- ligand at room temperature. CCDC: 898743, 1; 898744, 2. |
