本文通过水热法制备得到了一个新型二维金属有机配位聚合物[Co2(L1)(4,4’-bipy)(3H2O)·2H2O]n(1,H4L1=3,3’-(1,4-苯二氧基)二邻苯二甲酸;4,4’-bipy=4,4’-联吡啶),并对其结构进行了系统的表征。研究表明,3,3’-(1,4-苯二氧基)二邻苯二甲酸配体中的羧酸采用μ1-η1-η0和μ1-η1-η1两种桥联方式与2个钴离子配位形成十四圆环,形成的十四圆环被3,3’-(1,4-苯二氧基)二邻苯二甲酸配体连接进一步形成之字形的一维链状结构。最终,辅助配体4,4’-联吡啶将这些一维链状结构连接起来形成二维的(44)-sql网状拓扑结构。在本文中,我们还进一步研究了配位聚合物1的红外光谱以及热稳定性。
In this paper, a novel two-dimensional metal organic coordination polymer [Co2 (L1) (4,4’-bipy) (3H2O) · 2H2O] n (1, H4L1 = 3,3 ’- 4,4-bipy = 4,4’-bipyridine), and its structure was systematically characterized. The results show that the carboxylic acids in the 3,3 ’- (1,4-phenylenedioxy) diphthalic acid ligands have two kinds of bridging ways of μ1-η1-η0 and μ1-η1-η1 and two cobalt The ions coordinate to form a 14-membered ring, and the 14-membered ring formed by the 3,3 ’- (1,4-phenylenedioxy) diphthalic acid ligand further forms a zigzag one-dimensional chain structure. Finally, the ancillary ligand 4,4’-bipyridine links these one-dimensional chain structures together to form a two-dimensional (44) -sql network topology. In this paper, we further studied the IR spectra of coordination polymer 1 and its thermal stability.
