The preparation and X-ray structure of trans- [TcO2(14-ane-N2S2)]PF6 are described. The complex is obtained via a ligand exchange reaction of(n-Bu)4N- [TcOBr4] with 1,4-dithia-8,11-diazacyclotetradecane. The crystals are monoclinic, space group P21/n, with a=9.726(3), b=9.668(2), c=19.262(3) Å, β= 95.84(2)° and Z=4. The structure was solved by the heavy-atom method and refined using the full-matrix
描述了反式-[TcO 2(14-烷-N 2 S 2)] PF 6的制备和X射线结构。该配合物是通过(n-Bu)4 N- [TcOBr 4 ]与1,4-二硫代-8,11-二氮杂环十四烷的配体交换反应而获得的。晶体是单斜晶体,空间群P 2 1 / n,a = 9.726(3),b = 9.668(2),c = 19.262(3),β= 95.84(2)°,Z = 4。通过重原子方法解析结构,并使用全矩阵最小二乘法将结构精炼到R = 0.036和R w= 0.037。这两个离子的特征是存在由强分子间氢键产生的中心对称二聚体。
