| Abstract: Three zinc(Ⅱ), nickel(Ⅱ), and cobalt(Ⅱ) coordination polymers, namely {[Zn(μ3-pdba)(phen)]·H2O}n (1), {[Ni(μ3-pdba)(bipy)]·3H2O}n (2), and {[Co(μ3-pdba)(H2biim)(H2O)]·H2O}n (3) have been constructed hydrothermally using 4, 4'-(pyridin-3, 5-diyl)dibenzoic acid (H2pdba), 1, 10-phenanthroline (phen), 2, 2'-bipyridine (bipy), 2, 2'-biimdazole (H2biim), and zinc, nickel and cobalt 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 reveal that the three compounds crystallize in the monoclinic system, space groups P21/c or P21/n. Compounds1 and2 show 2D networks. Compound3 discloses a 1D ladder chain structure. The catalytic activities in the Henry reaction of these compounds were investigated. Compound1 exhibited an effective catalytic activity in the Henry reaction at 70 ℃. For this reaction, various parameters were optimized, followed by the investigation of the substrate scope. |
