The preparation and characterization of divalint copper nickel, cobalt and manganese complexes of some schiffbase ligands

الملخص EN

Co(II), Mn(ll), and Cu(II) Complexes of Schiff bases which are derived from the condensa(؛on of 3-amino-l ,2,4-triazole and salicylal-dehyde (Lj), p-hydroxy benzaldehyde (L2) and vaniline (L3) have been prepared and investigated by spectrophotometric, conductometric and analytical measurements.L1 is coordinated through the ؛minic nitrogen and phenolic oxygen atoms.

L2 and L3 are bonded through the Imino nitrogen and one ring nitrogen atoms as bidentate ligands.

Most of these complexes behave as a non-electrolyte while some as a 1:1 electrolyte.

The structural configurations have been proposed by the corresponding electronic transition.
