μ-aqua-pentaaqua[μ-3,6-bis(6-methyl-2-pyridyl)pyridazine]chlorodinickel(II) trichloride trihydrate

The title compound, mu-aqua-1:2 kappa(2)O-pentaaqua-1 kappa(2)O,2 kappa(3)O-mu-3,6-bis(6-methyl-2-pyridyl)pyridazine-1 kappa(2) N-1,N-6 :2 kappa(2)N(2),N-3-chloro-1 kappa Cl-dinickel(II) trichloride trihydrate, [Ni2Cl(C16H14N4)(H2O)(6)]Cl-3. 3H(2)O, consists of two Ni-II atoms, a 3,6-bis(6-methyl-2-pyridyl)pyridazine molecule, four Cl atoms and nine water molecules. The two Ni atoms are octahedrally coordinated by N and Cl atoms, and by water molecules, and the three six-membered rings, a pyridazine and two picolines, are planar to within 0.181 (3) Angstrom. The crystal structure is stabilized by an intra- and intermolecular hydrogen-bonding scheme involving water-water and water-chlorine interactions.
