Crystal structure, Hirshfeld surface analysis and DFT studies of tetra-kis-(μ-3-nitro-benzoato-κ : )bis-[(,-di-methyl-formamide-κ)copper(II)] di-methyl-formamide disolvate.

The title compound, [Cu(CHNO)(CHNO)]·(CHNO), is a binuclear copper(II) complex located on an inversion center midway between the two copper(II) cations. The asymmetric unit consists of one Cu cation, two 3-nitro-benzoato ligands, and two di-methyl-formamide (DMF) mol-ecules, one of which coordinates to the Cu cation and one is a solvate mol-ecule. The carboxyl-ate groups of the ligands bridge two Cu cations with a Cu-Cu distance of 2.
