通过四水合氯化锰(Ⅱ)与2,6-萘二酸在N,N-二甲基甲酰胺溶剂中的反应,获得了一种新的配位聚合物[Mn2(NDC)2(DMF)2(H2O)]n·nDMF (1). X射线单晶衍射分析表明,该配位聚合物属正交晶系,Pbca空间群,晶胞参数a=1.8334(2) nm, b=1.6046(17) nm, c=2.3706(3) nm, V=6.974(13) nm3, Z=8, Dc=1.471 g/cm3, Mr=772.50, μ=0.790 mm-1, F(000)=3176, S=0.951, (Δ/σ)max=0.001, Δρmax=0.539, Δρmin=-0.351,最后的一致性因子为R=0.0335, wR=0.0859.八面体锰(Ⅱ)离子与2,6-萘二酸配体的连接导致形成了无限的三维网状结构.该网状结构在b轴方向具有一维的菱形孔道(0.7 nm×1.2 nm),孔道的空穴被配位和非配位的溶剂分子所填充.

A new coordination polymer [Mn2(NDC)2(DMF)2(H2O)]n·nDMF (1) has been synthesized by the reaction of MnCl2·4H2O with 2,6-naphthalenedicarboxylic acids (H2NDC) under ambient conditions in DMF.A single crystal X-ray diffraction measurement reveals that 1 crystallized in the orthorhombic space group Pbca with a=1.8334(2) nm, b=1.6046(17) nm, c=2 .3706(3) nm, V=6.974(13) nm3, Z=8, Dc=1.471 g/cm3, Mr=772.50, μ=0.790 mm-1 , F (000)=3176, S=0 .951, ( Δ/σ )max=0.001, Δρmax=0 .539, Δρmin=-0.351, R=0.0335, wR=0.0859.The combination of octahedral manganese(Ⅱ) ions and NDC ligands leads to the formation of infinite three dimensional (3D) networks, which have lozenge-shaped 1D channels (0.7 nm×1 .2 nm) along the crystallographic b-axis.The cavities are filled with coordinated solvent molecules (DMF) and non coordinated ones.
