The FT-IR spectra of the complex indicate that ligand behave as a abidentate manner coordinating via nitrogen and sulphur for their structures and studied for structure activity relationship with complexes the anionic metal ligand complexes exhibit octahedral geometry. Thermal behaviour of these chealates show hydrated complexes losses water molecules of hydration in the first step. In thermogravitic analysis first step followed immediately by decomposition of the coordinated water, anions and ligands is the subsequent steps.</p> https://journalofchemistry.org/paper/885/ histamine structure activity relationship octahedral geometry
