Metal–organic frameworks (MOFs) are identified as one, among the most promising candidates to exploit Non-Linear Optics (NLO) behavior in the solid-state. Among them, non centrosymmetrically assembled MOFs are of particular interesting for imparting second-harmonic generation (SHG) property. Noncentrosymmetric Zn(3-ptz)2 MOF displays a moderate second harmonic generation (SHG) responses in powder form, however, SHG information is limited owing of  phase matching is not possible under the analysis conditions. To  achieve more accurate and reliable SHG, it is required to work with three-dimensional large size single crystals instead of  polycrystalline powder samples. Therefore, our work is focused on the growth of large sized single crystals  of Zn(3-ptz)2 by means of modification in reaction pH. We have found that the lowering of reaction pH favors the growth of  Zn(3-ptz)2 crystals. Crystallization kinetic analysis, theoretical calculations and experimental evidences explain the pH-effect on the crystallization of noncentrosymetric Zn(3-ptz)2 MOF.
