title: Diaqua-bis(picolinato N-oxide-κO,O')zinc(II).
abstract: In the title compound, [Zn(C(6)H(4)NO(3))(2)(H(2)O)(2)], the Zn atom is located on a centre of inversion and shows a distorted octa-hedral 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. Inter-molecular hydrogen bonds between aqua ligands and organic ligands link mol-ecules into a two-dimensional arrangement.
