Three coordination polymers based on quaternary‐ammonium‐modified isophthalic acid, namely, catena‐poly[[[aqua‐μ₂‐bromido‐di‐μ₃‐hydroxido‐methanoldinitratotetracopper(II)]‐bis{μ₄‐5‐[2‐(tripropylazaniumyl)ethoxy]benzene‐1,3‐dicarboxylato}] nitrate], {[Cu₄Br(C₁₉H₂₈NO₅)₂(NO₃)₂(OH)₂(CH₄O)(H₂O)]NO₃}_n, 1, poly[μ₃‐bromido‐μ₂‐bromido‐bromido‐μ₃‐hydroxido‐{μ₄‐5‐[2‐(tripropylazaniumyl)ethoxy]benzene‐1,3‐dicarboxylato}tricopper(II)], [Cu₃Br₃(C₁₉H₂₈NO₅)(OH)]_n, 2, and poly[bromido{μ₃‐5‐[2‐(tripropylazaniumyl)ethoxy]benzene‐1,3‐dicarboxylato}zinc(II)], [ZnBr(C₁₉H₂₈NO₅)]_n, 3, were obtained by solvothermal reactions. Coordination polymer (CP) 1 contains tetranuclear Cu₄ units, in which the four Cu atoms are linked by two μ₃‐OH⁻ groups into a Cu₄(OH)₂ 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 Cu₄(OH)₂ cluster and these are linked with CuBr₃ 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 Zn₂ units and cpa⁻ ligands. The Br⁻ counter‐anions of the quaternary ammonium groups all take part in the construction of the polymeric networks.
