当用卤素溶液处理时,络合物Au(C 6 F 5)(tht)经历氧化加成,得到Au(C 6 F 5)X 2(tht)(X = Cl,Br或I)。后者的四氢噻吩配体可被中性或阴离子配体取代,分别得到中性络合物Au(C 6 F 5)X 2 L(L = IVB,VB或VIB组配体)或阴离子络合物[Au( C 6 F 5)X 2 X'] -(X'= Cl或SCN)。

Addition of a bidentateligand (LL = 1,10-phenanthroline, o-phenylenebis(dimethylarsine)) to solutions of Au(C6F5)X2(tht) (X = Cl, Br; tht = tetrahydrothiophene) leads to potentially five-coordinate gold(III) derivatives. 197Au Mössbauer spectroscopy points, however, to four-coordinate square-planar complexes with a weak penta-coordination in the phen-containing derivatives. The complexes react with
在Au(C 6 F 5)X 2(tht)(X = Cl,Br; tht =四氢噻吩)的溶液中添加双齿配体(LL= 1,10-菲咯啉,邻苯撑双(二甲基ar ))潜在的五配位金(III)衍生物。197 AuMössbauer光谱学指出,在含phen的衍生物中五坐标配位较弱的四坐标方平面络合物。配合物与AgClO 4反应,得到[Au(C 5 F 5)X(LL)] ClO 4或[Au(C 6 F 5)(PPh 3)(LL)类型的四配位阳离子配合物)](二氧化氯4)2。
