Three coordination polymers based on quaternary‐ammonium‐modified isophthalic acid, namely, catena ‐poly[[[aqua‐μ 2 ‐bromido‐di‐μ 3 ‐hydroxido‐methanoldinitratotetracopper(II)]‐bis{μ 4 ‐5‐[2‐(tripropylazaniumyl)ethoxy]benzene‐1,3‐dicarboxylato}] nitrate], {[Cu 4 Br(C 19 H 28 NO 5 ) 2 (NO 3 ) 2 (OH) 2 (CH 4 O)(H 2 O)]NO 3 } n , 1 , poly[μ 3 ‐bromido‐μ 2 ‐bromido‐bromido‐μ 3 ‐hydroxido‐{μ 4 ‐5‐[2‐(tripropylazaniumyl)ethoxy]benzene‐1,3‐dicarboxylato}tricopper(II)], [Cu 3 Br 3 (C 19 H 28 NO 5 )(OH)] n , 2 , and poly[bromido{μ 3 ‐5‐[2‐(tripropylazaniumyl)ethoxy]benzene‐1,3‐dicarboxylato}zinc(II)], [ZnBr(C 19 H 28 NO 5 )] n , 3 , were obtained by solvothermal reactions. Coordination polymer (CP) 1 contains tetranuclear Cu 4 units, in which the four Cu atoms are linked by two μ 3 ‐OH − groups into a Cu 4 (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 Cu 4 (OH) 2 cluster and these are linked with CuBr 3 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 2 units and cpa − ligands. The Br − counter‐anions of the quaternary ammonium groups all take part in the construction of the polymeric networks.
