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 sRSC advancesSynthesis, 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.PMC905463221471017Li HHan ASu HXu GKhan MAfalseSynthesis, 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.Acylhydrazone Schiff bases are rich in N and O atoms to coordinate with metal ions to form multidentate complexes.
