Abstract
Reaction of H3salmp (H3salmp = 2-bis(salicylidieneamino)methylphenol) and lanthanide ions has afforded three lanthanide-schiff base complexes. One is homodinuclear [Nd(Hsalmp)(NO3)(EtOH)]2·2EtOH (1), other two are heteroleptic tetranuclear [LnNa(salmp)(sal)(EtOH)3]2 (Ln = Nd (2), Ce (3); sal = salicylaldehydato) architectures. In complex 1, the counter Hsalmp2– anions adopt NO3 donor sets, wheras in complexes 2 and 3, the counter salmp3– anions select N2O3 donor sets and sal– anions chose O2 donor sets, in which cleavage of C=N groups in ligand has taken place. The amount of alkali has displayed a vital influence on preparation of these complexes. Both of the complexes were elucidated by elemental analysis, IR, fluorescence spectra and X-ray crystallography.
