    The wide range of ligands and metals led to an extensive development of coordination chemistry. These compounds have been studied due to possible applications in several fields, as catalysis and nonlinear optics. The crystal structure of a coordination compound allows to establish a direct relation between structure and properties. Among the ligands, nitrogen aromatic compounds have been used largely in synthesis, since they enable strong coordination bond and stable intermolecular interactions, increasing also the possibility to study them in the crystalline state. This work reports the synthesis, crystal structure, infrared and UV-Vis spectroscopy of a Zn(II) complex with 2-aminopyrazine (ampyz) and water as ligands, resulting in the formula [Zn(H2O)4(ampyz)2][Zn(H2O)6](SO4)2(H2O)2. Moreover, to illustrate the intermolecular interactions, we also report the analysis of the Hirshfeld surface and its fingerprint for the main complex [Zn(H2O)4(ampyz)2]2+.
