N. Rath et al., STABILITY-CONSTANTS OF COBALT(II), NICKEL(II) AND ZINC(II) COMPLEXES OF SOME TETRADENTATE IMINE-PHENOL LIGANDS, Journal of the Indian Chemical Society, 75(3), 1998, pp. 160-161
The stability constants of bivalent Co, Ni and Zn with Schiff base der
ived ligands have been determined potentiometrically by Calvin-Bjerrum
technique as adopted by Irving and Rossotti and spectrophotometricall
y by Job's method of continuous variation in 80% (v/v) DMSO-water medi
um at 35 +/- 0.1 degrees and ionic strength of 0.2 mot dm(-3).
