摘要
Adduct formation of nickel(II) and copper(II) Schiff base complexes, (NiL) and (CuL), as donors with diorganotin(IV) dichlorides as acceptors has been investigated spectrophotometrically, in acetonitrile. L is alpha,alpha'-Me-2-salen, N,N'-ethylenebis(alpha-methylsalicylideneiminate) (1), alpha,alpha'-Me-2-salen, N,N'-1,2-propylenebis(alpha-methylsalicylideneiminate) (2), alpha,alpha'-Ph-2-salen, N,N'-ethylenebis(alpha-phenylsalicylideneiminate) (3), and alpha,alpha'-Ph-2-salen, N,N'-1,2-propylenebis(alpha-phenylsalicylideneiminate) (4). The trend of adduct formation of the nickel(II) and copper(II) Schiff base complexes with a given tin compound decreases as follows: M(alpha,alpha'-Me-2-salen) > M(alpha,alpha'-Me-2-salpn) > M(alpha,alpha'-Ph-2-salen) > M(alpha,alpha'-Ph-2-salpn). The trend of the reaction of R2SnCl2 toward a given nickel(II) or copper(II) Schiff base complex is Ph > Me > Bu. The trend of the metal reactivity in a given Schiff base toward a given diorganotin(IV) dichloride at the same temperature is Cu(II) > Ni(II).
