| 摘要: 通过新合成的吡啶基羧酸席夫碱配体（5-(吡啶基-3-亚甲基氨基)间苯二甲酸H2L），和镍盐反应制备了一个新的镍配合物{[Ni(HL)2(H2O)2]·2H2O}n(1)，利用元素分析及X-射线单晶衍射对其进行了表征。结构分析结果表明标题化合物属于三斜晶系，P1 空间群，晶胞参数为a=0.764 79(11) nm，b=0.870 49(13) nm，c=1.081 13(16) nm，α=85.583(2)°，β=82.614(2)°，γ=81.565(2)°，V=0.704 82(18) nm3，Z=1，Dc=1.586 g·cm-3，μ=0.763 mm-1，F(000)=350。在配合物的结构中，Ni(Ⅱ)的配位构型为畸变的八面体。配合物中每个配体通过羧酸氧和吡啶氮原子和金属配位形成一维链状结构，并通过体系中丰富的氢键作用链接成为三维框架并加以稳定。 | |

| Abstract: A novel nickel(Ⅱ) coordination polymer {[Ni(HL)2(H2O)2]·2H2O}n (H2L=5-((pyridin-3-ylmethyl)amino)isophthalic acid) (1) has been synthesized by the reaction of Ni(NO3)2·6H2O and H2L under hydrothermal condition. The structure of 1 was determined by single-crystal X-ray diffraction. Complex 1 crystallizes in triclinic space group P1 with a=0.764 79(11) nm, b=0.870 49(13) nm, c=1.081 13(16) nm, α=85.583(2)°, β=82.614(2)°, γ=81.565(2)°, V=0.704 82(18) nm3, Z=1, Dc=1.586 g·cm-3, μ=0.763 mm-1 and F(000)=350. The coordination environment of Ni(Ⅱ) is octahedral, and each ligand links two Ni(Ⅱ) atoms using its pyridyl N atom and carboxylate O atom to generate an infinite one-dimensional (1D) chain structure. The 1D chains are further connected by hydrogen bonds to give a three dimensional structure. CCDC: 769438. | |
