Semiorganic single crystals of bis-glycine manganese chloride (BGMC) of dimension 5 × 3 × 3 mm³ were grown from aqueous solution by slow evaporation method at room temperature. The crystal structure and lattice parameters were determined for the grown crystal by the single crystal X-ray diffraction studies. BGMC was subjected to FT-IR and FT-Raman spectral analyses. The lower cutoff wavelength observed from UV–vis–NIR transmittance spectrum is 271 nm. The mechanical strength of the grown crystal was estimated using Vickers microhardness tester. The dielectric response of the grown crystal was analyzed at different temperatures in the frequency range from 50 Hz to 2 MHz. Thermal properties were investigated by thermogravimetric, differential thermal and differential scanning calorimetric analyses. Chemical etching study shows the distribution of etch figures of various shapes in the grown single crystal. The third order nonlinear optical properties of BGMC were investigated by Z-scan technique employing He–Ne laser radiation of wavelength at 632.8 nm.
