Abstract
새로운 유기주석(IV) 착물을 Bu2SnCl2 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, 119Sn NMR 및 원소분석을 통하여 전반적으로 특성을 분석하였다. 분광학적인 데이터로부터 리간드는 산소원자 를 통하여 주석에 배위됨을 알았으며, 배위수가 4임을 용액에서 119Sn NMR 데이터에 의해 결정하였다.

A novel organotin(IV) complex has been prepared from Bu2SnCl2 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 SnBuCl2L is formed. This complex was fully characterized by IR, 1H NMR and 119Sn 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 119Sn NMR data in solution.
