Aquabis(4-formylbenzoato-? O )(1,10-phenanthroline-? 2 N , N ')zinc(II)

The Zn atom in the title complex, [Zn(C8H5O3)2(C12H8N2)(H2O)], is coordinated by two O atoms of formyl­benzoate carboxyl­ate groups, two N atoms of a 1,10-phenanthroline ligand and one water mol­ecule, giving rise to a square-pyramidal coordination geometry. Adjacent complex mol­ecules are linked into a one-dimensional chain structure via π–π stacking inter­actions, with centroid–centroid distances of 3.531 (3) and 3.664 (3) A.
