title: trans-Diaqua-bis-[2-(2-pyrid-yl)acetato-κN,O]nickel(II).
abstract: In the centrosymmetric title complex, [Ni(C(7)H(6)NO(2))(2)(H(2)O)(2)], the Ni(II )atom, located on an inversion center, is six-coordinated in a distorted octa-hedral geometry defined by two N and four O atoms from the two chelating 2-(2-pyrid-yl)acetate ligands and two aqua ligands. The mol-ecules form a three-dimensional framework by O-H⋯O hydrogen bonds and aromatic π-π stacking inter-actions, with a centroid-centroid distance of 3.506 (3) Å.
