Synthesis, Characterisation and Biological Studies of Some Mn(II), Fe(II), Co(II), Ni(II), and Cu(II) Complexes of Schiff Base Derived from Vanillin and 1, 2-Diaminoethane.

Abstract

Some transition metal complexes with bis-3-(p-hydrosy-m-methoxy benzylidene amino)-1, 2-diaminoethame (HMBADE) have been synthesized with the general compostion ML₂X₂ (M = Mn²⁺, Fe²⁺, CO²⁺, Ni²⁺ and Cu²⁺, X = Cl^–, Br^– or I^– and L = HMBADE). Their structural features have been investigated on the basis of elemental analysis, molar conductivity, electronic,¹H, n.m.r and IR spectral data.
