In the title compound, [Ni(C28H18N2O 2)], the NiII centre has a square-planar coordination geometry in which the Schiff base ligand acts as a cis-O,N,N′,O′- tetra-dentate ligand. The crystal structure

Three ligands have been formed by the 1:2 molar condensation of o-phenylenediamine with salicylaldehyde, 2-hydroxy-1-naphthaldehyde or o-hydroxyacetophenone. The potentially tetradentate ligands are N,N-bis(salicylaldehyde)-o-phenylenediamine (SalophHsub

Complexes of iron(II), cobalt(II) and nickel(II) with four tetradentate (ONNO) Schiff base ligands viz. salicylaldehyde o-phenylenediimine (Salophen) salicylaldehyde metaphenylenediimine (Salmphen), 2-hydroxy-1-naphthaldehyde o-phenylenediimine (Nalophen) and 2-hydroxy-1-naphthaldehyde m-phenylenediimine (Nalmphen) are shown to have aromatic diimine dependent structural features.Although, Salophen complexes are known, complexes of FeII, CoII and NiII with Salmphen, Nalophen and Nalmphen Schiff base ligands are prepared and characterised by various physicochemical and spectral studies.While Salophen and Nalophen give monomeric and low-spin complexes, the ligands prepared using metaphenylenediamine form binuclear complexes presumably due to longer chain length and less steric strain present in the latter ligands.The structural characterisation of a group of complexes are presented.In addition, organocobalt complexes of Salophen and Nalophen are prepared and characterised.
