Abstract The solvent evaporation technique synthesized the metal complexes of Dibromidobis{2-[(2-chlorophenyl)methylidene]hydrazine-1-carbothioamide}-cadmium [CdL2Br2] under optimum conditions. The [CdL2Br2] crystallizes with a space group Cc with a monoclinic crystal system. FTIR and Raman spectrum affirms the presence of all expected the functional group. UV-VIS absorption analysis shows high absorption at 314 nm and the energy gap was found to be 3.37 eV. TG-DTA analysis confirms the crystalline nature and thermal stability of the material. Photoluminescence analysis demonstrates that the materials have an emission peak at 412.07 nm in the violet light region. Grown crystal confirms it is very much essential for the second harmonic generation (SHG) and frequency conversion applications.
