- Department of Chemistry, Agra University, Agra-282 010 Manuscript received 27 April 1987, revised 8 February 1988, accepted 19 February 1988 The formation of ternary metal(II)/thiophene-2-carboxylic acid/pyridine-2-carboxylic acid complexes with CoII, NiII, CuII and ZnII, has been studied potentiometrically at 25 and 40±1° and constant ionic strength (μ = 0.1 M KNO,) in aqueous solution. The stability order was found to be Cull > NiII > CoII > ZnII. pH-metric results were further supported by characterisation of some of the isolated complexes.
