4-di(1H-imidazol-1-yl)benzene (dib). Compounds (UO2)(HL1) (1) and Zn(H2O)3(UO2)2(O)(OH)(L2)·H2O (2) are constructed by semirigid ligands. The former is a one-dimensional ribbon-like structure with UO7 pentagonal bipyramids as the building unit, while the latter adopts a tetramer of UO7 pentagonal bipyramids to build a layered structure. Mononuclear UO7 pentagonal bipyramids are connected by L3 groups to generate
通过使用各种羧基配体3,3'-(((2-((3-羧基苯氧基)甲基)-2-甲基丙烷-1,3-二基)双(氧基))二苯甲酸(H 3 L 1),4,4'-(3-(4-羧基苯乙基)-3-羟基戊烷-1,5-二基)二苯甲酸(H 3 L 2),氯胺酸(H 2 L 3)和苯甲酸(HL 4)在含N的大肠菌存在下,包括2,2'-联吡啶(bipy),1,10-菲咯啉(phen),1-([1,1'-联苯] -4-基)-1 H-咪唑(bpi)和1,4-二(1 H-咪唑-1-基)苯(dib)。化合物(UO 2)(HL 1)(1)和Zn(H 2 O)3(UO 2)2(O)(OH)(L 2)·H 2 O(2)由半刚性配体构成。前者是一维带状结构,以UO 7五角形双锥体为构建单元,而后者则采用UO 7五角形双锥体的四聚体来构建分层结构。单核UO 7五角双锥通过L 3基团连接,以生成UO 2(L 3)(H 2 dib)0.5(
