Three novel Schiff base adducts [SnMe2Cl2(Hcdacacen)] (1), [SnBu2Cl2(Hcdacacen)2] (2) and [SnPh2Cl2(Hcdacacen)2] (3) have been synthesized by reaction of SnR2Cl2 (R = Me, Bu and Ph) with a new Schiff base ligand methyl-2-[2-(acetylacetoneimino)ethylamino]-1-cyclopentene-1-dithiocarboxylate (Hcdacacen). The ligand and complexes were characterized by elemental analysis and spectroscopic studies. Spectroscopic data suggest that Hcdacacen exists predominately in ketamine tautomeric form and in all complexes acts as a monodentate neutral ligand coordinates to the metal through oxygen atom, while the sulfur atom and imine nitrogen is not involved in the coordination to the tin.

具有新型多功能席夫碱配体的新型二有机锡(IV)氯化物加合物:合成和光谱性质

通过反应合成了三种新颖的席夫碱加合物[SnMe 2 Cl 2(Hcdacacen)](1),[SnBu 2 Cl 2(Hcdacacen)2 ](2)和[SnPh 2 Cl 2(Hcdacacen)2 ](3)。 SnR 2 Cl 2的(R = Me,Bu和Ph)与新的席夫碱配体-2- [2-(2-(乙酰丙酮亚氨基)乙基氨基] -1-环戊烯-1-二硫代羧酸甲酯(Hcdacacen)。通过元素分析和光谱研究表征了配体和配合物。光谱数据表明,麦角六肽主要以氯胺酮互变异构形式存在,并且在所有络合物中均作为单齿中性配体通过氧原子与金属配位,而硫原子和亚胺氮不参与与锡的配位。
