The synthesis, crystal structure and properties of a zinc(II) coordination polymer viz . [Zn 2 (μ‐OH)(μ 2 ‐η 1 :η 1 ‐3‐mba) 3 ] 1 (3‐mba=3‐methoxybenzoate) based on 3‐methoxybenzoic acid is described. The three crystallographically independent μ 2 ‐η 1 :η 1 3‐mba ligands and the unique μ‐hydoxide ligand link the two unique Zn(II) ions into an infinite chain of {Zn 2 O 7 } bitetrahedra with alternating Zn⋅⋅⋅Zn separations of 3.314 and 3.364 Å respectively. The carboxylate carbons of the symmetric bridging 3‐mba ligands serve as links between the adjacent bitetrahedra in the coordination polymer. Pyrolysis of 1 results in the formation of highly agglomerated ZnO particles having spherical morphology. 1 exhibits blue fluorescence.
