The formation constant of Tm(III)-systems with different sulphonanilide ligand namely 3-carboxy-4-hydroxy-2’-chloro benzene sulphonanilide, 3-carbmethoxy-4-hydroxy-2’-chloro benzene sulphonanilide and 3-carbethoxy-4-hydroxy-2’-chloro benzene sulphonanilide have been determined with the help of spectrophotometeric method. Results shows that the stability of lanthanide complexes is found similar to [Ag(NH3)2]+ type of complex

Formation constant; Tm(III)-sulphonanilide complex
