Di-μ-chlorido-bis{chlorido[2-(2-furylmethyliminomethyl)pyridine-κ2 N,N′]nickel(II)}

The title dinuclear nickel(II) complex, [Ni2Cl4(C11H10N2O)2], lies on a centre of symmetry located at the centroid of the four-membered ring formed by the two Ni atoms and the bridging chloride ions. The NiII atom is five-coordinated in a square-pyramidal geometry by the imine and pyridine N atoms of the Schiff base ligand, and by one terminal and two bridging Cl atoms. The Ni⋯Ni distance is 3.506 (2) Å. The O atom of the furan substituent in the ligand unit is not involved in coordination to the Ni atom.
