| 摘要: 采用水热方法，选用5-（2-羧基苯基）吡啶-3-甲酸配体（H2cpna）与1，2-二（4-吡啶基）乙烷（dpea）或1，2-二（4-吡啶基）乙烯（dpey）分别与NiCl2·6H2O和ZnCl2在160℃下反应，合成了2个三维配位聚合物{[Ni （μ3-cpna）（μ-dpea）0.5]·H2O}n（1）和{[Zn （μ3-cpna）（μ-dpey）0.5]·H2O}n（2），并对其结构、催化和摩擦性质进行了研究。研究表明，在室温条件下化合物2在Knoevenagel缩合反应中显示出较好的催化活性。同时，2在聚α-烯烃合成润滑剂中显示出有效的抗磨性能。 |

| Abstract: Two nickel(Ⅱ) and zinc(Ⅱ) coordination polymers, namely {[Ni(μ3-cpna)(μ-dpea)0.5]·H2O}n (1) and {[Zn(μ3-cpna)(μ-dpey)0.5]·H2O}n (2) have been constructed hydrothermally using 5-(2-carboxyphenyl)nicotinic acid (H2cpna), 1,2-di(4-pyridyl)ethane (dpea), 1,2-di(4-pyridyl)ethylene (dpey), and nickel and zinc chlorides at 160℃. The products were isolated as stable crystalline solids and were characterized by IR spectra, elemental analyses, thermogravimetric analyses, and single-crystal X-ray diffraction analyses. Single-crystal X-ray diffraction analyses revealed that two compounds crystallize in the monoclinic or orthorhombic systems, space groups, P21/c or Pbca. Both compounds show 3D metal-organic frameworks. Compound 2 exhibited an effective catalytic activity in the Knoevenagel condensation reaction at room temperature. Meanwhile, compound 2 showed an effective anti-wear performance in poly-α-olefine synthetic lubricant. |
