New ligands meso- and dl-bis(ethanoylacetone)-stilbenediimine meso- and dl-bis(n-propanoylactone)-stilbenediimine and their copper and nickel complexes have been prepared. The reagents and their metal complexes have been characterized using IR, UV, visible and mass spectroscopic techniques. The coloured copper and nickel complexes are studied spectrophotometrically and their DTA, TGA curves are recorded. The metal complexes particularly of dl-isomer indicate reasonable thermal stabilities, the metal complexes are eluted on OV101 on chromosorb column using GLC equipped with flame ionization detector and detection limits are found in ng range of metal ions.
