Popis: | In the title complex, [Cu(2-nitrobenzoate)2(tmeda)], the central metal atom has distorted square-planar geometry with one oxygen atom each from two 2-nitrobenzoate ligands and two TMEDA ligand nitrogen atoms. 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-κ2 N,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 R 2 2(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%). |
