UNEXPECTED C=N BOND CLEAVAGE IN H3salmp: SYNTHESIS AND STRUCTURES OF [LnNa(salmp)(sal)]2·6EtOH (Ln = Sm, Er; H3salmp = 2-BIS(SALICYLIDIENEAMINO)METHYLPHENOL; sal = SALICYLALDEHYDATO)

Аннотация

The reaction of LnCl3 with Na3salmp/H3salmp (H3salmp = 2-bis(salicylidieneamino)methylphenol) affords [LnNa(salmp)(sal)]2 (Ln = Sm( = 1 \* ROMAN I), Er( = 2 \* ROMAN II); sal = salicylaldehydato) complexes being different from the known Ln-salmp complex of [Sm(salmp)(THF)]2. In the reaction, the cleavage of C=N bonds happens in H3salmp, and the regenerated salicylaldehydato anion arises and takes part in the coordination. Both complexes are characterized by elemental analysis, IR spectroscopy, and X-ray crystallography.
