Abstract In this study, we coordinate the Schiff base 4-{[(1E)-(2-Hydroxyphenyl)methylidene]amino}-1,5-dimethyl-2-phenyl-1,2 dihydro-3H-pyrazol-3-one, C18H17N3O2 with zinc ions to form a new coordination compound with chemical formula C36H36N6O4Zn. This is the first effort to determine the vibrational properties of the C36H36N6O4Zn using infrared and Raman spectroscopy combined with Density functional based methods (DFT). The vibrational modes analyses were performed based on Potential Energy Distribution (PED). A comparison of theoretical and experimental spectra allowed us to assign most of the normal modes of the crystal and interpreted the experimental findings. According to our results, the zinc ions coordinated with two imine nitrogens and two pyrazolone oxygens.
