A series of 5-(4′-alkylphenylazo)-3-phenylamino-2-thioxothiazolidin-4-one (HLn) have been prepared and characterized by elemental analysis, 1H NMR and IR spectra. X-ray diffraction pattern of ligand (HL2) was studied. The geometrical structures of these ligands are carried out by HF method with 3-21G basis set.
