Abstract: In the title mononuclear complex, [Zn(C6H4NO3)2(H2O)2], the six-coordinate ZnII atom adopts an octahedral coordination geometry and is located on an inversion centre. There is a weak - stacking interaction between adjacent pyridyl rings [the separation between the centroids of the pyridyl rings is 3.840 (2) Å and the perpendicular distance is 3.582 Å]. The crystal packing is stabilized by O-HO and N-HO hydrogen bonds.
