yields the non-oxo V′” complex [V(S′N′O)2] 2, derived from the Schiff base HS′N′OH, where 0 and S′ are phenolate and thiophenolate functions, respectively, and N′ is the Schiff base (enamine) nitrogen. Complex 2, with the ligands in a distorted trigonal-antiprismatic array, is a rare example of a structurally characterized complex where the Schiff base is preserved at the expense of its thiazoline tautomeric
四齿,中性二硫化物[双(硫醚)]配体1,6-双(ø -吡啶基)-2,4- dithiahexane,NSSN,与发生反应[VCI 2(TMEDA)2 ],以形成八面体(清一色顺式; ç 2V -对称)配合物[的VCl 2(NSSN)] 1,第一低价的钒配合物,其中所述硫代功能是只有机硫化物。用邻巯基苯胺处理(VOCl 2(thf)2 ] ,然后与邻羟基萘乙醛反应,生成非羰基V'''络合物[V(S'N'O)2 ] 2衍生自席夫碱HS'N'OH,其中0和S'分别为酚盐和硫酚盐官能团,而N'为席夫碱(烯胺)氮。复杂2,在畸变三角-反棱柱阵列的配位体,是一种罕见的示例的,其中席夫碱在其噻唑啉的互变异构形式的代价保存了结构表征复杂。
