摘　　要：通过混合溶剂热法合成了一例锰基配位聚合物(pyH)_(2)[Mn_(3)(1,4-NDC)_(4)]·4H_(2)O(1)(1,4-NDCH_(2)=1,4-萘二甲酸,py=吡啶),并对其结构进行了表征.单晶X-射线分析显示化合物1结晶于非心空间群Cc,a=1.17245(3)nm,b=3.06350(8)nm,c=1.43958(4)nm,β=95.155(3)°,V=5.1498(2)nm^(3),Z=4.邻近的Mn(Ⅱ)离子通过羧基基团-OCO^(-)以及羧基上的μ_(2)-O连接构成一维(1D)链;每条1D链通过1,4-NDC配体连接到邻近的4条1D链构成三维(3D)骨架结构.热重分析表明,孔道中的晶格水分子可以通过加热完全脱除,而不影响主体骨架结构.A Mn-based coordination polymer(pyH)_(2)[Mn_(3)(1,4-NDC)_(4)]·4H_(2)O(1)(1,4-NDCH_(2)=1,4-naphthalenedicarboxylic acid,py=pyridine)has been solvothermally synthesized and characterized.Single-crystal X-ray diffraction analysis reveals that 1 crystallizes in the noncentrosymmetric space group Cc with a=1.17245(3)nm,b=3.06350(8)nm,c=1.43958(4)nm,β=95.155(3)°,V=5.1498(2)nm^(3),Z=4.The adjacent Mn(Ⅱ) ions are bridged by the-OCO^(-) groups and μ_(2)-O(carboxylate oxygen atoms),forming an infinite 1D chain.Each 1D chain is connected to adjacent four 1D chains through the 1,4-NDC ligands,giving rise to a 3D framework.TGA reveals that lattice water molecules in the channels can be completely removed by heating and the framework is not destroyed.
