NEW COPPER(Ⅰ) AND COBALT(Ⅱ) BINUCLEAR COMPLEXES WITH MERCAPTOBENZOTHIAZOLE AND MANNICH BASE LIGANDS: A SPECTROSCOPIC CHARACTERIZATION

摘要

The new cobalt(Ⅱ) and copper(Ⅰ) mixed-ligand complexes with 2-mercaptobenzo-thiazole [Hmbt] and one of the Mannich bases N,N'-bis(antipyryl-4-methyl)-piperazine [BAMP] or N,N'-tetra-(antipyryl-4-methyl)-l,2-diaminoethane [TAMEN] were synthesized, and characterized by elemental analyses, conductometric and magnetic susceptibility measurements, UV-VIS, IR and Raman spectroscopy. They belong to the following types: Co_2(BAMP)(Hmbt)_2X_4·2H_2O where X = NCS, C1O_4; Co_2(TAMEN)(Hmbt)_2X_4 where X = NCS, ClO_4; Cu_2(BAMP)(mbt)_n (ClO_4)_2·4H_2O and Cu_2 (TAMEN)(mbt)_n (ClO_4)_2·2H_2O and Cu_2(BAMP)(mbt)_n(SCN)_2H_2O. The bonding of 2-mercaptobenzothiazole through the endocyclic nitrogen is proved. Molecular modeling calculations with the MM+ force field also support the proposed structures.
