Synthesis, characterisation and biological activity for binuclear complexes with Co (II)‎, Cu (II)‎ and Zn (II)‎ with new ligand m-phenylendi (azo-2-naphthol)‎ ligand type N2O2

الملخص EN

In this work, the (m-phenylenediamine) and (2-naphthol) have been used in the synthesis of tetradentate ligand [m-phenylenedi (azo-2-naphthol)] [H2L] type (N2O2).

The ligand was refluxed in the ethanol with the metal ions [Co (II), Cu (II) and Zn (II)] salts, using triethyleamine as a base in (2 : 2) molar ratio to give the binuclear complexes.

These complexes were characterised by (A.

A), F.

T.I.

R, (U.

V-Vis) sp ectroscopies, along with conductivity, chloride content and melting point measurement.

These studies revealed an octahedral geometries for Co (II), Cu(II) and Zn (II) complexes with the general structure M 2 (L)2 (H2O)4].

The ligand and its complexes exhibited biological activity against the Bacillus (G+) strain and the Pseudomonase (G) strains.
