TLDR
In this article, the reaction of the anion B12H-B′ with [Au(Ph3P)Cl] in acetonitrile was studied and the nature of the initial cation of the closo-dodecaborate and the reagent ratio was shown to affect complexing.Abstract:
The reaction of the anion B12H

with [Au(Ph3P)Cl] in acetonitrile was studied. The nature of the initial cation of the closo-dodecaborate and the reagent ratio was shown to affect complexing. The X-ray structures of compounds Au(Ph3P)2[AgB12H12] (I) and [Au9(Ph3P)8]B24H23 (II) were determined. Complex I is the first example where B12H
