Abstract :The ligand-field parameters Dq,p` and p of pseudo-octahedral Niinsert ignore into journalissuearticles values(H); complex of N-insert ignore into journalissuearticles values(2- hydroxyphenyl);-salicylaldimine and twelve different derivatives were calculated. Substituent effects on these parameters are discussed. Dq values were found to be higher and p values to be lower in those complexes bearing electron withdrawing NO2 groups, than the respective values in the unsubstituted parent complex. On the other hand, Dq`s were found to be lower and P`s to be higher in complexes carrying electron donating groups like CH3., C1 and Br in comparison with those of the parent complex.
