English Abstract

The work reported deals with the preparation and characterization of a number of new complexes of manganese (II).

The complexes are formed by the reaction of the mentioned metal salts with three ligands of Schiff base type; the ligands are: dibenzoinlidenemalonoyldihydrazide (L1H4), dibenzoinlidenesuccinyldihydrazide (L2H4) and dibenzoinlidenephthalolyldihydrazide (L3H4).

The prepared complexes have been characterized by molar conductance, CHN analysis, metal contents,electronic spectra, infrared spectra, and magnetic susceptibility measurements.

The different studies suggest that all the complexes are hexacoordinated with octahedral geometry in the neutral medium; the ligands formed cationic complexes of the type [Mn(LH4)]X2 were X=Cl-1and NO3-1 , while in a basic medium anionic complexes of the general formula K2[Mn(L)].
