KEYWORDSThe complexation behaviour of some salophen,s derivatives with few transition and heavy metal cations in N,N'-dimethyl formamid as nonaqueous solvent at 25 o C and 0.05 M tetra ethylammonium perchlorate to investigate the effect of structure were studied by spectrophotometric method. The formation of complexes between ligands and metal ions of the types ML, ML2 or M2L was observed. The overall stability constants of such complexes were evaluated by computer refinement of absorption-mole ratio data using the KINFIT program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
