【Abstract】 Four new organotin complexes based on m-phthaloyl bis（substituted salicylaldehyde acylhydrazone）（H₄L）,（Sn R²）₂L （1-4）,were synthesized by solvothermal reaction of H₄L with R₃²SnOH,or one-pot solvothermal reaction of m-phthaloyl hydrazide,3-tert-butyl salicylaldehyde,and tricyclohexyltin hydroxide,where H₄L=m-Ph（CONH—N=CH（o-OH）PhR¹）₂;R¹=NEt₂,R²=Ph （1）;R¹=3,5-di-tert-butyl=3,5-t-2Bu,R²=Ph （2）;R¹=3,5-t-2Bu,R²=Cy （3）;R¹=3-tert-butyl=3-t-Bu,R²=Cy （4）.And they were characterized by elemental analysis,IR,and (¹H,¹³C,and ¹¹⁹Sn) NMR.The structures of complexes 1-4 were confirmed by X-ray diffraction.Three“inward E-type”complexes 1-3 were formed by the inward orientation of two substituted salicylaldehyde acylhydrazone chains of H₄L and coordination with tin atoms.And two substituted salicylaldehyde acylhydrazone chains were oriented outward and coordinated with tin atoms to form an“outward E-type”complex 4.Complexes 1,2,and 4 belong to the triclinic ■ space group and complex 3 belongs to the monoclinic P2₁/c space group.The central tin and the coordination atom form a five-coordinate distorted triangular bipyramids configuration.The fluorescence properties of the ligands and the complexes-chloroform solution showed that when free ligand m-Ph（CONH—N=CH（o-OH）Ph NEt₂）₂（H₄L¹） with weak fluorescence and ligand m-Ph（CONH—N=CH（o-OH）Ph（3,5-t-2Bu））₂（H₄L²） without fluorescence coordinated with phenyltin or cyclohexyltin,the chloroform solution of the complexes emitted strong fluorescence.CCDC:2111478,1;2111479,2;2111480,3;2111481,4.更多还原
