Abstract

In the title compound, {[Zn(C12H8O4)(C12H8N2)(H2O)]·0.5H2O}n, each ZnII atom is six-coordinated by two N atoms from one 1,10-phenanthroline (phen), three carboxylate O atoms from two different L ligands [H2L = 3,3′-(p-phenylene)diacrylic acid] and one water molecule in a distorted octahedral environment. The two L dianions are situated across inversion centres and bridge neighbouring ZnII centres, yielding a chain propagating parallel to [100]. O—H...O hydrogen bonds between the coordinated water molecule, the solvent water molecule (half-occupied) and the carboxylate O atoms further stabilize the structure.
