Abstract

In the title compound, [Zn(C6H4NO3)2(H2O)2], the Zn atom is located on a centre of inversion and shows a distorted octa­hedral coordination geometry. Two aqua ligands occupy the axial positions and four O atoms of the two chelating picolinic acid N-oxide ligands are located in the equatorial plane. Inter­molecular hydrogen bonds between aqua ligands and organic ligands link mol­ecules into a two-dimensional arrangement.
