【Abstract】 The bis（3-ethoxysalicylaldehyde） 1,3-benzyldiacyl hydrazone （H₄L） ligand was prepared by the reaction of 3-ethoxysalicylaldehyde with benzene-1,3-dicarbohydrazide in ethanol solution.Bis（3-ethoxysalicylaldehyde） 1,3-benzyldiacyl hydrazone tetrabutyl（phenyl）ditin,Bu₄Sn₂L （T1） and Ph₄Sn₂L （T2）,were synthesized by solvothermal reaction of H₄L with dibutyltin oxide and triphenyltin hydroxide in methanol,respectively.The structures of ligand and complexes were characterized by elemental analysis,IR,UV-Vis spectroscopy,NMR,and single-crystal X-ray diffraction.The molecular formula of H₄L is C₂₆H₂₆N₄O₆.The crystal of H₄L belongs to the monoclinic system and space group C2/c.Two formylhydrazide （3-ethoxy）salicylaldehydes are cis-symmetric configuration.The molecular formula ofT1is C₄₂H₅₈N₄O₆Sn₂.The crystal ofT1belongs to the orthorhombic system and space group Pbcn.The two formylhydrazide （3-ethoxy）salicylaldehyde chains of H₄L turn inward 180°,and a distorted trigonal bipyramid is formed by the coordination of coordinating atoms with tin.The molecular structure is axis-symmetric about C2…C4.The molecular formula ofT2is C₅₀H₄₂N₄O₆Sn₂.The crystal ofT2belongs to the triclinic system,space group P1.One formylhydrazide （3-ethoxy）salicylaldehyde of H₄L keeps the original configuration,and the other formylhydrazide （3-ethoxy）salicylaldehyde turns inward 180°.Two coordination chains with different configuration orientations were formed,which coordinated with diphenyltin to form a binuclear trans-asymmetric distorted trigonal bipyramid complexes.The fluorescence properties of trichloromethane solutions of H₄L,T1,T2(50μmol·L^-1) were tested.The results showed that H₄L had weak fluorescence at 520 nm,andT1andT2had 14-15 times stronger fluorescence emission peaks than the ligand at 518 nm.CCDC:2092625,H₄L;2092626,T1;2092627,T2.更多还原
