摘　　要：采用水热方法,选用醚氧桥联四羧酸配体H_(4)dia与菲咯啉(phen)、2,2′-联吡啶(bipy)或双(4-吡啶基)胺(bpa)分别与CoCl_(2)·6H_(2)O、CuCl_(2)·2H_(2)O和CdCl_(2)·4H_(2)O在160℃下反应,得到了一个一维链结构[Co2(μ4-dia)(phen)2(H_(2)O)2]n(1)和2个三维网络结构的配位聚合物[Cu2(μ6-dia)(bipy)2]n(2)和{[Cd2(μ5-dia)(μ-bpa)2(H_(2)O)]·H_(2)O}n(3),并对其结构和催化性质进行了研究。研究表明,在50℃下配合物2在Knoevenagel缩合反应中显示出很好的催化活性。Three cobalt(Ⅱ)),copper(Ⅱ),and cadmium(Ⅱ) coordination polymers,namely[Co2(μ4-dia)(phen)2(H_(2)O)2]n(1),[Cu2(μ6-dia)(bipy)2]n(2),and{[Cd2(μ5-dia)(μ-bpa)2(H_(2)O)]·H_(2)O}n(3)have been constructed hydrothermally using H_(4)dia(5-(2,5-dicarboxyphenoxy)isophthalic acid),phen(phen=1,10-phenanthroline),bipy(2,2′-bipyridine),bpa(bis(4-pyridyl)amine),and cobalt,copper and cadmium chlorides at 160℃.The products were isolated as stable crystalline solids and were characterized by IR spectra,elemental analyses,thermogravimetric analyses,and singlecrystal X-ray diffraction analyses.Single-crystal X-ray diffraction analyses reveal that three compounds crystallize in the monoclinic or triclinic systems,space groups P21/n,P21/c,or P1.Compound 1 discloses a 1D double-chain structure.Compounds 2 and 3 show 3D frameworks.The catalytic activity in the Knoevenagel condensation reaction of these compounds was investigated.Compound 2 exhibited excellent catalytic activity in the Knoevenagel condensation reaction at 50℃.CCDC:2209559,1;2209560,2;2209561,3.
