Abstract
Dinuclear complexes of Mn(II), Fe(II) and Zn(II) were synthesized by using the mononuclear complexes of such metals as precursor. These dinuclear complexes formed by the inter- complex Schiff base reaction. The physicochemical data were established by metal estimation and elemental analysis. The effective magnetic moment and electronic spectral data supported the tetrahedral environment of the metal ions. Spectroscopic methods like infrared spectroscopy, UV-visible spectroscopy and thermal analysis were used for structure elucidation of the complexes. Mass spectrometry was used for confirmation of molecular mass and fragmentation pattern of the complexes. Powder diffraction pattern suggested the crystalline nature with the tetragonal symmetry of the complexes.
