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-κN]zinc(II)]-µ2-benzene-1,4-dicarboxylato-κ(2)O(1):O(4)], [Zn(C8H4O4)(C18H16N2O2)(H2O)]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)(H2O)]n chains which are interlinked through (aqua)O-H···O hydrogen-bonding interactions, producing two-dimensional corrugated sheets.
