Abstract: The reaction of copper(II) sulfatepentahydrate with 2-nitro­benzoic acid and N,N,N′,N′-tetra­methyl­ethylenedi­amine (TMEDA) in basic solution produces the complex bis­(2-nitro­benzoato-κO)(N,N,N′,N′-tetra­methyl­ethylenedi­amine-κ²N,N′)copper(II), [Cu(C₇H₄NO₄)₂(C₆H₁₆N₂)] or [Cu(2-nitro­benzoate)₂(tmeda)]. Each carboxyl­ate group of the 2-nitro­benzoate ligand is coordinated by Cuᴵᴵ atom in a monodentate fashion and two TMEDA ligand nitro­gen 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 via a R₂²(10) ring motif. These ribbons are linked by further C—H⋯O hydrogen bonds, leading to two-dimensional hydrogen-bonded arrays parallel to the bc plane. Weak π–π stacking inter­actions provide additional stabilization of the crystal structure. Hirshfeld surface analysis, dₙₒᵣₘ and two-dimensional fingerprint plots were examined to verify the contributions of the different inter­molecular contacts within the supra­molecular structure. The major inter­actions of the complex are O⋯H/H⋯O (44.9%), H⋯H (34%) and C⋯H (14.5%).
