The glycine based single crystals such as glycine zinc sulphate (GZS) and di(glycine) barium chloride (DGBC) was synthesized and single crystals are grown by solution growth technique. The unit cell parameters of grown crystals have been analyzed by single crystal XRD. The optical properties were studied using UV-Vis and photoluminescence spectroscopies. The TG/DTA analyzes were performed and the melting point of the sample was measured. The study of microhardness was measured on a prominent plane to determine mechanical strength using Vicker's hardness test. The NLO properties measurements were carried out using Q-switched Nd: YAG laser.

The article highlights the study of the synthesis of a complex
combination of p-nitrobenzoic acid with Cu2+from aromatic carbonic acid
derivatives. Influencing factors on the synthesis of complex compounds in the
room were studied. Specifically, the time dependence of the reaction, the effect
of temperature, the concentration dependence wasobserved in practice. The
synthesized complex was evaluated by means of IR-Fourier spectrometry,
elemental analysis, mass spectrometry, TG-DSK and X-ray structural analysis to
determine its chemical structure, as well as to justify that the new complex is
thermally and chemically steady.
