A New Zn(II) Azido Complex of L-Arginine: X-ray Crystal Structure, Hirshfeld, and AIM Studies

The synthesis and X-ray crystal structure analyses of the azido complex [Zn(N3)(Arg)2](N3)·3H2O, where Arg is L-arginine, were presented. molecular was further studied using FT-IR spectra as well atoms in molecules (AIM) theory. An analysis data indicated monoclinic system P21 space group with a = 13.0283(5) Å, b 15.2032(7) c 13.3633(6) β 114.3580(10)°, V 2411.28(18) Å3, Z 4. Two [Zn(N3)(Arg)2](N3)·3H2O formulae represent asymmetric unit this geometric parameters both units are slightly different. In central Zn(II) ion penta-coordinated two bidentate ligand one terminally coordinated azide ion. Each located trans to another via N O amino carboxylate groups, respectively. Hence, five-coordinated has distorted square pyramidal coordination geometry. supramolecular inspected Hirshfeld analysis. O···H (26.6–28.4%), H···H (32.3–35.3%), N···H (30.4–34.0%) contacts most significant interactions complex. Zn–N, Zn–O bonds have slight covalent based on AIM study.
