Crystal structure of bis-[?-meth-oxy(pyridin-2-yl)methano-lato-?(3) N,O:O]bis[chlorido-copper(II)].


ABSTRACT: The racemic title compound, [Cu2(C7H8NO2)2Cl2], is composed of dinuclear mol-ecules in which meth-oxy(pyridin-2-yl)methano-late ligands bridge two symmetry-related Cu(II) ions. Each Cu(II) ion is coordinated in a square-planar geometry by one Cl atom, the N and O atoms of the bidentate ligand and the bridging O atom of the centrosymmetrically related bidentate ligand. The separation between the two Cu(II) atoms is 3.005?(1)?Å. In the crystal, non-classical C-H?O hydrogen bonds, weak ?-? stacking [centroid-centroid distance = 4.073?(1)?Å] and weak electrostatic Cu?Cl inter-actions [3.023?(1)?Å] link the dinuclear mol-ecules into chains running parallel to the b axis. These chains are further connected by weak C-H?Cl hydrogen bonds directed approximately along the a axis, forming a three-dimensional supra-molecular network.
