CHROMIUM (III) METAL COMPLEXES WITH A SCHIFF BASES DERIVED FROM 2-HYDROXY-1- NAPHTHALDEHYDE

Chromium (III) Complexes of the type M(L-L),have been synthesized from Schiff bases derived from 2-hydroxy-1-naphthaldehyde.The complexes  were characterized using microanalysis, infrared, UV/ visible and molar conductivity. Microanalysis results have revealed that the metal (III) complexes were formed in 1:2 molar ratio (M : L). Infrared studies have shown that the complexes coordinated through the azomethine nitrogen and phenolic oxygen of the ligands. The UV/ visible showed broad bands in the visible region which are probably due to d-d transitions of the metal ions. Molar conductivity results showed that the complexes are non-electrolytes.
