摘　　要：采用间苯二(取代水杨醛酰腙)(H_(4)L)与R^(2)_(3)SnOH溶剂热反应,或间苯二甲酰肼、3-叔丁基水杨醛和三环己基氢氧化锡一锅溶剂热法反应,合成了4个新的有机锡配合物(SnR_(2))_(2)L(1~4),其中,H_(4)L=m-Ph(CONH—N=CH(o-OH)PhR^(1))2;R^(1)=NEt_(2),R^(2)=Ph(1);R^(1)=3,5-di-tert-butyl=3,5-t-2Bu,R^(2)=Ph(2);R^(1)=3,5-t-2Bu,R^(2)=Cy(3);R^(1)=3-tert-butyl=3-t-Bu,R^(2)=Cy(4)。经元素分析、红外光谱和(^(1)H、^(13)C、^(119)Sn)核磁共振谱表征,并用X射线衍射方法确证配合物1~4的结构。配体H_(4)L的2个取代水杨醛酰腙链向内取向并与锡原子配位形成3个内向E型配合物1~3,取代水杨醛酰腙链向外取向并与锡原子配位形成外向E型配合物4。配合物1、2和4属于三斜晶系P1空间群,配合物3属于单斜晶系P21/c空间群。中心锡与配位原子构成畸形双角三锥构型。配体、配合物-三氯甲烷溶液的荧光性能表明,当具有弱荧光的配体m-Ph(CONH—N=CH(o-OH)PhNEt_(2))_(2)(H_(4)L^(1))和无荧光的配体m-Ph(CONH—N=CH(o-OH)Ph(3,5-t-2Bu))_(2)(H_(4)L^(2))分别与苯基锡、环己基锡配位后,配合物-三氯甲烷溶液发出强荧光。Four new organotin complexes based on m-phthaloyl bis(substituted salicylaldehyde acylhydrazone)(H_(4)L),(SnR_(2))_(2)L(1-4),were synthesized by solvothermal reaction of H_(4)L with R^(2)_(3)SnOH,or one-pot solvothermal reaction of m-phthaloyl hydrazide,3-tert-butyl salicylaldehyde,and tricyclohexyltin hydroxide,where H_(4)L=m-Ph(CONH—N=CH(o-OH)PhR^(1))2;R^(1)=NEt_(2),R^(2)=Ph(1);R^(1)=3,5-di-tert-butyl=3,5-t-2Bu,R^(2)=Ph(2);R^(1)=3,5-t-2Bu,R^(2)=Cy(3);R^(1)=3-tert-butyl=3-t-Bu,R^(2)=Cy(4).And they were characterized by elemental analysis,IR,and(^(1)H,^(13)C,and^(119)Sn)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 H_(4)L 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 P1 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)PhNEt_(2))_(2)(H_(4)L^(1))with weak fluorescence and ligand m-Ph(CONH—N=CH(o-OH)Ph(3,5-t-2Bu))_(2)(H_(4)L^(2))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.
