通过一锅反应制备了4′-(3-甲氧基-4-羟基苯基)-2,2′∶6′,2″-三联吡啶(L),通过重结晶的方法得到了其醋酸盐单晶体(HL)(CH3COO)(1),并以L为配体组装了过渡金属配合物[Cu(NO3)(CH3OH)L](NO3)(2)和[Zn(NO3)2L](C2H5OH)(3),通过元素分析、IR光谱和单晶X-射线衍射等表征了3个化合物的结构。结果表明,化合物1中,三联吡啶环呈反-反构型,而在2和3中,三联吡啶环呈现出顺-顺构型,然后采取三齿螯合模式连接金属离子形成单核单元。3个化合物中,三联吡啶分子之间以及它们与溶剂分子之间形成的氢键、π-π堆积和范德华力等相互作用将化合物1~3的单核单元连接形成三维网状结构。
The 4 ’- (3-methoxy-4-hydroxyphenyl) -2,2’6’, 2 "-terpyridine (L) was prepared by one- The transition metal complexes [Cu (NO3) (CH3OH) L] (NO3) (2) and [Zn (NO3) 2L] (C2H5OH ) (3) The structures of the three compounds were characterized by elemental analysis, IR spectra and single crystal X-ray diffraction.The results showed that in the compound 1, the terpyridine ring was in the trans- , The terpyridine ring shows a cis-cis configuration, and then adopts a tridentate chelating mode to connect metal ions to form a mononuclear unit. Among the three compounds, three hydrogen bonds between the terpyridine molecules and between them and the solvent molecules, π -π stacking and van der Waals forces interacting the mononuclear units of compounds 1-3 to form a three-dimensional network.
