| 摘要: 采用间苯二（取代水杨醛酰腙）（H4L）与R32SnOH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（SnR2）2L（1~4），其中，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）。经元素分析、红外光谱和（1H、13C、119Sn）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H4L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） PhNEt2）2（H4L1）和无荧光的配体m-Ph（CONH—N=CH（o-OH） Ph（3，5-t-2Bu））2（H4L2）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。 |

| Abstract: Four new organotin complexes based on m-phthaloyl bis(substituted salicylaldehyde acylhydrazone) (H4L), (SnR2) 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 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) PhNEt2) 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. |
