摘要：

A UV-Vis spectrophotometric study of adduct formation of SalenH2 (1) and M-II(Salen), where M = Mn (2), Fe (3), Co (4), Ni (5) and Cu (6) as donors with Me2SnCl2 as acceptor have been investigated in chloroform. Adducts (1a-6a) have been characterized by H-1, C-13 and Sn-119 NMR, IR and electronic spectroscopy and microanalysis. Formation constants and thermodynamic parameters were measured for 1 : 1 and 2 : 1 adducts at various temperatures (T = 278 to 308 K). The data refinement was carried out with the SQUAD 84 program. The trend of formation constants of M-II(Salen) complexes with Me2SnCl2 follows the order: Mn>Fe>Cu>Co>Ni. The formation constants for the free 1 and MII(Salen) with Me2SnCl2 changes according to the following trend: MII(Salen)SalenH2
