The reaction of copper(II) sulfatepentahydrate with 2-nitro-benzoic acid and ,,','-tetra-methyl-ethylenedi-amine (TMEDA) in basic solution produces the complex bis-(2-nitro-benzoato-κ)(,,','-tetra-methyl-ethylenedi-amine-κ,')copper(II), [Cu(CHNO)(CHN)] or [Cu(2-nitro-benzoate)(tmeda)]. Each carboxyl-ate group of the 2-nitro-benzoate ligand is coordinated by Cu atom in a monodentate fashion and two TMEDA ligand nitro-gen atoms are coordinate by the metal center, giving rise to a distorted square-planar coordination environment. In the crystal, metal complexes are linked by centrosymmetric C-H⋯O hydrogen bonds, forming ribbons a (10) ring motif. Read More
