The crystal structure of new Cu(II) coordination compound synthesized using the triethanolammonium 4-nitrobenzoate (HTEA)(4NB), namely bis(4-nitrobenzoato)-bis(μ-2-[bis(2-hydroxyethyl)amino]ethan-1-olato)-di-copper(II) dihydrate [Cu₂(TEA)₂(4NB)₂]·2H₂O, is reported. The compound consists of centrosymmetric dinuclear units, in which two Cu(II) ions are bridged by two μ:η₁ oxo bridges of two TEA anions, adopting a NO₅ distorsional tetragonal bipyramidal geometry. Dinuclear complexes are hydrogen-bonded with outer-sphere water molecules by intermolecular O–H···O hydrogen bond interactions in a 1D supramolecular chain and further interlinked by C–H···π stacking interactions. The relationship between noncovalent interactions derived from Hirshfeld surface analysis, two-dimensional fingerprint plots and crystal lattice energy of the compound is also presented and discussed.
