Abstract

The stepwise stability constant of Zn(II), Cu(II), Ni(II) and Co(II)
complexes with 2´-hydroxy-4´-,5´-dimethyl-4-chlorochalcone oxime are
calculated in 75% dioxane-water mixture at 25ºC and ionic strength
0.1M(NaClO4). It is observed that the overall stability constants are in
the order of Cu(II) > Zn(II) > Ni(II) > Co(II).
