Seven novel aluminium complexes supported by Schiff base ligands derivedfrom o‐diaminobenzene or o‐aminothiophenol were synthesized and characterized. The reactions of AlMe3 with L1 (N,N′‐bis(benzylidine)‐o‐phenylenediamine) and L2 (N,N′‐bis(2‐thienylmethylene)‐o‐phenylenediamine) gave the complexes L1AlMe3 (1) and L2AlMe2 (2), respectively, which involved two types of reaction mechanisms: one was

mixed ligand Cu(II), Zn(II), Ni(II) and Co(II) complexes of the type [MLX]Cl 2 where X=1,10-phenonthroline and ligand (L) have been synthesised from the condensation of thiophene-2-carboxaldehyde with o -phenylenediamine. They were characterised by elemental analysis, molar conductance, magnetic susceptibility, infrared, electronic absorption, protonmagneticresonance and mass spectralstudies. An octahedral
