摘要: Adduct formation between R2SnCl2 (R = methyl and phenyl) PhSnCl3 as acceptors Cu(II) complexes of tetradentate Schiff-base ligands [CuL], where L [Salen, bis(salicylaldehyde)ethylenediimine], [3-MeOSalen, N,N′-bis(3-methoxysalicylaldehyde)ethylenediimine], [5-MeOSalen, N,N′-bis(5-methoxysalicylaldehyde)ethylenediimine], [5-BrSalen, N,N′-bis(5-bromosalicylaldehyde)ethylenediimine], [salpn, N,N′-bis(salicylaldehyde)1,3-propanediimine], [Salophen, bis(salicylaldehyde)phenylenediimine], [3-MeOSalophen, N,N′-bis(3-methoxysalicylaldehyde)phenylenediimine], [5-MeOSalophen, N,N′-bis(5-methoxysalicylaldehyde)phenylenediimine], donors have been investigated in acetonitrile by UV-Vis spectrophotometric analysis. The constants thermodynamic free energies were measured using titration for 1 : adduct at various temperatures (T 293–313 K). trend copper with a given tin acceptor decreases follows: ; the r...
