Hydrothermal Synthesis and Crystal Structure of a Mn(Ⅱ) Coordination Polymer

使醋酸锰与α-萘乙酸(C10H7CH2COOH)、4,4′-联吡啶(4,4′-bipy)水热反应,合成了配位聚合物{[Mn(C10H7CH2COO)2(H2O)2(4,4′-bipy)].4H2O}n.通过红外、元素分析以及晶体结构测试表征了所得到配合物的结构.单晶X射线测试表明,该配合物是由4,4′-bipy桥联多个金属锰(Ⅱ)离子形成的一维{[Mn(4,4′-bipy)]n长链,α-萘乙酸根离子的氧原子以单齿形式与中心金属离子配位,悬挂于长链的两侧.研究了这个配合物的荧光性能和热稳定性.

By hydrothermal reaction of Mn（ CH3CO0） 2 with 1-naphthylacetic acid and 4,4′-bipy, 1-D coordination polymer { [ Mn （ C to H7 CH2 COO） 2 （ H2O） 2 （4,4′-bipy） ] · 4H2O}, was prepared. Its structure was confirmed by X- ray structural diffraction, elemental analysis and IR data. In the complex, the Mn（Ⅱ） ions are connected by 4,4′- bipy forming one-dimensional chain with C10HTCH2COO-units acting as monodentate ligands in the side chain. Researched on the thermal and fluorescent property of the compound.
