Synthesis of Copper(II) Complex with 1,10-Phenanthroline and Nitrate Anion in the Presence of Mandelic Acid and the Crystalline Structure of This Complex

The synthesis of a complex compound based on divalent copper as a complexing agent and 1,10-phenanthroline and nitrate ion as ligands has been described for the first time. The obtained complex, being linked with mandelic acid by hydrogen bonds, associates it in the external sphere. The interest in these ligands is caused by their potential biological activity and possibility of using them in pharmaceutics. The composition of the synthesized metal complex is found to be [Cu(1,10-phen)(2)NO3](C8H8O3 center dot NO3), as confirmed by elemental analysis. The molecular and crystal structures of the complex are studied by X-ray diffraction (XRD). Its crystallographic characteristics, bond angles, lattice parameters, and geometry of hydrogen bonds are determined. The data obtained made it possible to construct a 3D model of the material. A Hirshfeld surface analysis of the metal complex, performed using the Crystal Explorer program, showed the presence of hydrogen bonds in it, which stabilize its crystal structure.
