Diaquabis[2-(2-hydroxyethyl)pyridine-κ2 N,O]cobalt(II) dichloride

Abstract

In the title salt, [Co(C7H9NO)2(H2O)2]Cl2, the CoII cation, located on an inversion center, is N,O-chelated by two hydroxyethylpyridine ligands and coordinated by two water molecules in a distorted O4N2 octahedral geometry. In the crystal, the Cl- anions link with the complex cations via O - H⋯Cl hydrogen bonds, forming a three-dimensional supramolecular architecture. π-π stacking is observed between the pyridine rings of adjacent molecules [centroid-centroid distance = 3.5810 (11) Å].
