Synthesis, crystal structures, and luminescent properties of Zn(ii), Cd(ii), Eu(iii) complexes and detection of Fe(iii) ions based on a diacylhydrazone Schiff base.

ABSTRACT: Acylhydrazone Schiff bases are rich in N and O atoms to coordinate with metal ions to form multidentate complexes. In this study, a novel diacylhydrazone Schiff base (N'¹ E,N'⁴ E)-N'¹,N'⁴-bis(2-hydroxy-5-nitrobenzylidene)succinohydrazide (H₄L) was synthesized from the condensation of nitrosalicylaldehyde and succinic dihydrazide. The interactions of H₄L with common monovalent, divalent and trivalent metal ions were investigated by ultraviolet spectroscopy and fluorescence spectroscopy. The results showed that H₄L had no obvious effect on the monovalent metal ions (Li⁺, Na⁺, K⁺), but reacted with most divalent and trivalent metal ions, and s
