trans-Diaquadichlorooxovanadium(IV) bis[2-(2-pyridylamino)pyridinium] dichloride

J. Hartung, P. Schmidt, I. Svoboda and H. Fuess

Abstract: The neutral complex trans-[VOCl₂(H₂O)₂] co-crystallizes with di-2-pyridylamine hydrochloride to provide the title compound, (C₁₀H₁₀N₃)₂[VCl₂O(H₂O)₂]Cl₂. The V-bound aqua ligands form two hydrogen bonds each. The amine functionality of the 2-(2-pyridylamino)pyridinium cation participates as a monovalent donor in the hydrogen bonding. In both instances, interstitial Cl^- ions serve as hydrogen-bond acceptors. The three hydrogen bonds that are formed per anion give rise to one-dimensional chains along [100].
