Abstract The crystal of bis glycine hydro bromide was harvested from the slow evaporation method at room temperature and it was subjected to the single crystal XRD study for confirmation which ensures that the grown crystal has P212121space group with orthorhombic structure. The PXRD analysis shows crystalline nature of the title crystal. The various functional groups present in the crystal were analyzed by the FT-IR and FT-Raman spectroscopy techniques. The optical band gap was determined by the UV-Visible spectroscopy analyzes. The SEM with EDX analyzes shows that the grown crystal has smooth surface and well defined shape. The elemental composition study confirms the presence of elements in the title crystal. The antimicrobial activity of title crystal was tested against the four different micro-organisms by disc diffusion method. This result reveals that the parent and its complex crystals have no antibacterial effect.
