trans-Diaquabis[2-(2-pyridyl)acetato-κ2N,O]nickel(II)

Abstract

In the centrosymmetric title complex, [Ni(C7H6NO2)2(H2O)2], the NiII atom, located on an inversion center, is six-coordinated in a distorted octahedral geometry defined by two N and four O atoms from the two chelating 2-(2-pyridyl)acetate ligands and two aqua ligands. The molecules form a three-dimensional framework by O—H...O hydrogen bonds and aromatic π–π stacking interactions, with a centroid–centroid distance of 3.506 (3) Å.
