Abstract
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.

As part of our ongoing interest in the structure of nickel(II) complexes (Zhu et al, 2003), we report the crystal structure of the title compound, a new centrosymmetric dinuclear nickel(II) complex, (I), Fig. 1, derived from the Schiff base ligand furan-2-ylmethyl-(1-pyridin-2-ylmethylidene)amine
