| Abstract: Two cobalt(Ⅱ) coordination polymers, namely [Co2(μ3-deta)(H2biim)3(H2O)2]n (1) and {[Co2((μ6-deta)(phen)2]·H2O}n (2), have been constructed hydrothermally using H4deta (2, 3, 3', 4' - diphenyl ether tetracarboxylic acid), H2biim (2,2'-biimidazole), phen (1,10-phenanthroline), and cobalt chloride 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 compounds 1 and 2 crystallize in the triclinic and monoclinic systems, space groups P1 and P21/c, respectively. Compound 1 discloses a 1D chain structure, and compound 2 features a 2D network. The catalytic activities in Knoevenagel condensation reaction of the compounds were investigated. Compound 1 exhibited excellent catalytic activity in Knoevenagel condensation reaction at room temperature. |
