In this work, a new complex compound based on 4-nitroftalic acid and ethylenediamine of composition [C8H3NO6]2−·(C2H10N2)2+ was synthesized for the first time. The complex compound was grown from solution by slow evaporation, and its crystal structure was determined by X-ray structural analysis. According to the results of the study, the complex belongs to the monoclinic syngony and has a space group of P21/c. Deprotonation of the 4-nitroftalate anion and protonation of ethylenediamine were observed in the crystal structure. Intermolecular and intramolecular hydrogen bonds were shown to play an important role in the stabilization of the crystal lattice. A Hirshfeld surface analysis of the complex compound was performed, and the nature of the intermolecular interactions in the crystal structure was evaluated. Additionally, the geometric parameters of the compound were optimized using quantum chemical DFT calculations. The obtained results demonstrate the promising prospects of nitroftalate-based molecular complexes for crystal engineering and the creation of functional materials.
