Chemistry Department, M. M. College, Khekra-201 101 Manuscript received 28 November 1982, revised 12 October 1981, accepted 8 June 1985 Complexes of TiIV and ZrIV with Schiff base ligands N-4-methyl-7-hydroxy-8- acetocoumarinylidene anthranilic acid (H2MHACAA) and N-4-methyl-7-hydroxy-8- acetocoumarinylidene-o-aminophenol (H2MHACAP) have been isolated and charac­terised on the basis of various physicochemical studies. Infrared spectral data show 'bat the ligands art as tridentate chelating agents coordinating through phenolic oxygen, azomethine nitrogen and carboxylic oxygen
