Abstract
Ni(II), Cu(II), Ag(I) and Hg(II) form 1:2 (metal-ligand) complexes wit h 4'-morpholinoacetophenone thiosemicarbazone. The stability constants of these complexes in 60% (v/v) aqueous DMF were determined at differ ent ionic strengths (0.07, 0.13 and 0.20 M) and at different temperatu res (25, 30, 35 and 40 +/- 0.1-degrees-C) using a spectrophotometric m ethod. From these constants, the thermodynamic stability constants and thermodynamic parameters (DELTAG(formal), DELTAH(formal), DELTAS(form al)) were calculated.
