摘要
以3,5-二(吡啶-4-甲氧基)苯甲酸(HL)为配体合成了2个配合物:[BaL2]n(1)和[PbL(Ox)0.5]n(2)(H2(Ox)为草酸),并通过元素分析,红外光谱,热重和X-射线单晶衍射实验对其结构进行了表征。分析表明,1由L-连接形成二维结构,通过苯环之间的π…π作用连接成三维网络结构;2由于主配的连接形成二维层状结构,再通过辅配连接形成拓扑符号为(43)(44.5.617.72.82)(4.52)的三维网络结构。
Two new coordination polymers [BaL2], (1) and [PbL(Ox)0.5]n (2) (HL=3,5-bis(pyrid-4-ylmethoxy)benzoic acid, H2(Ox)=Oxalic acid) have been synthesized under hydrothermal reaction and characterized by single crystal X-ray diffraction analysis. 1 displays a 2D framework and further enlarged its dimensionality to 3D net by π-π interactions between benzene rings with a centroid-centroid distance of 0.360 88(1) nm. 2 possesses a 3D (3,8)- connected net with the (4^3)(4^4.5.6^17.7^2.8^2)(4.5^2) topology. Thermogravimetric analyses (TGA) have been measured for both compounds.
