Synthesis and Characterization of a Novel Organotin Complex: Di(n-butyl) chloro[5-(p-dimethylaminobenzylidene)rhodanine]tin(IV) Based on a Competing N, O, and S Donor Ligand

새로운 유기주석(IV) 착물을 $Bu_2SnCl_2$과 N, O 및 S 주개 리간드인 5-(p-dimethylaminobenzylidene)rodanine(HL)로 부터 제조하였다. 염기 존재 하에 리간드는 탈양성자화되며, SnBuCl2L의 분자식을 갖는 착물이 형성되었다. 이 착물은 IR, $^1H$ NMR, $^{119}Sn$ NMR 및 원소분석을 통하여 전반적으로 특성을 분석하였다. 분광학적인 데이터로부터 리간드는 산소원자를 통하여 주석에 배위됨을 알았으며, 배위수가 4임을 용액에서 $^{119}Sn$ NMR 데이터에 의해 결정하였다. A novel organotin(IV) complex has been prepared from $Bu_2SnCl_2$ and the N, O and S donor ligand, 5-(p-dimethylaminobenzylidene) rodanine (HL). The ligand is deprotonated in the presence of a base and the complex with the general formula $SnBuCl_2L$ is formed. This complex was fully characterized by IR, $^1H$ NMR and $^{119}Sn$ NMR and elemental analysis. Spectroscopic data indicate the ligand is coordinated through the oxygen atom to the tin and the coordination number of four is supported by $^{119}Sn$ NMR data in solution.
