A helical zinc(II) coordination polymer assembled from 1,3‐bis[(pyridin‐3‐yl)methoxy]benzene and benzene‐1,4‐dicarboxylic acid

In catena ‐poly[[aqua[1,3‐bis(pyridine‐3‐ylmethoxy)benzene‐κ N ]zinc(II)]‐μ 2 ‐benzene‐1,4‐dicarboxylato‐κ 2 O 1 : O 4 ], [Zn(C 8 H 4 O 4 )(C 18 H 16 N 2 O 2 )(H 2 O)] n , each Zn II centre is tetrahedrally coordinated by two O atoms of bridging carboxylate groups from two benzene‐1,4‐dicarboxylate anions (denoted L 2− ), one O atom from a water molecule and one N atom from a 1,3‐bis[(pyridin‐3‐yl)methoxy]benzene ligand (denoted bpmb). (Aqua)O—H...N hydrogen‐bonding interactions induce the formation of one‐dimensional helical [Zn( L )(bpmb)(H 2 O)] n chains which are interlinked through (aqua)O—H...O hydrogen‐bonding interactions, producing two‐dimensional corrugated sheets.
