Three coordination polymers based on quaternary-ammonium-modified isophthalic acid, namely, catena-poly[[[aqua-μ-bromido-di-μ-hydroxido-methanoldinitratotetracopper(II)]-bis{μ-5-[2-(tripropylazaniumyl)ethoxy]benzene-1,3-dicarboxylato}] nitrate], {[CuBr(CHNO)(NO)(OH)(CHO)(HO)]NO}, 1, poly[μ-bromido-μ-bromido-bromido-μ-hydroxido-{μ-5-[2-(tripropylazaniumyl)ethoxy]benzene-1,3-dicarboxylato}tricopper(II)], [CuBr(CHNO)(OH)], 2, and poly[bromido{μ-5-[2-(tripropylazaniumyl)ethoxy]benzene-1,3-dicarboxylato}zinc(II)], [ZnBr(CHNO)], 3, were obtained by solvothermal reactions. Coordination polymer (CP) 1 contains tetranuclear Cu units, in which the four Cu atoms are linked by two μ-OH groups into a Cu(OH) cluster, which are in turn linked by 5-[2-(tripropylazaniumyl)ethoxy]benzene-1,3-dicarboxylate (cpa) ligands into a chain structure. CP 2 also contains a tetranuclear Cu(OH) cluster and these are linked with CuBr units into chains. The chains are then connected by cpa ligands into a two-dimensional layered structure. CP 3 contains a two-dimensional layer structure built by binuclear Zn units and cpa ligands. The Br counter-anions of the quaternary ammonium groups all take part in the construction of the polymeric networks.
通过溶剂热反应得到了三种基于季铵化间苯二甲酸的配位聚合物，即链状聚[[[水合-μ-溴-二-μ-羟基-甲醇二硝酸根四铜(II)]-双{μ-5-[2-(三丙基铵基)乙氧基]苯-1,3-二羧酸根}]硝酸盐]，{[CuBr(CHNO)(NO)(OH)(CHO)(HO)]NO}，1；聚[μ-溴-μ-溴-溴-μ-羟基-{μ-5-[2-(三丙基铵基)乙氧基]苯-1,3-二羧酸根}三铜(II)]，[CuBr(CHNO)(OH)]，2；以及聚[溴-{μ-5-[2-(三丙基铵基)乙氧基]苯-1,3-二羧酸根}锌(II)]，[ZnBr(CHNO)]，3。配位聚合物(CP)1包含四核铜单元，其中四个铜原子通过两个μ-OH基团连接成一个Cu(OH)簇，该簇又通过5-[2-(三丙基铵基)乙氧基]苯-1,3-二羧酸根(cpa)配体连接成链状结构。CP 2也包含一个四核Cu(OH)簇，并且这些簇与CuBr单元连接成链。然后这些链通过cpa配体连接成二维层状结构。CP 3包含由双核锌单元和cpa配体构建的二维层状结构。季铵基团的Br抗衡阴离子都参与了聚合物网络的构建。
