Department of Chemistry, Punjab Agricultural University, Ludhiana-141 004 Manuscript received 6 February 1981, revised 30 December 1981, accepted 2.9 May 1982 The stepwise stability constants of complexes of Co(II), Ni(II) or Cu(II) with methylsalicylate, ethylsalicylate or phenylsalicylate have been determined. The effect of temperature and ionic strength has been studied. The thermodynamic stability constants are obtained at 25°. The stability order is Cu(II) > NI(II) > Co(Il) and
