Abstract

[(Cp*Fe)3{(η3-As3)Fe}As6] and [(Cp*Fe)3As6][FeCl3(THF)], Two New Ironarsenide Cluster Containing As6 and As3 Fragments The compounds [(Cp*Fe)3{(η3-As3)Fe}As6] (1) and [(Cp*Fe)3As6][FeCl3(THF)], (2) can be obtained in good yields through the reaction of As7(SiMe3)3 with FeCl2 and LiCp*. Both compounds have been characterized by mass spectroscopy and crystal structure analysis. The As7 nortricyclane frame of As7(SiMe3)3 is still recognizable in 1. According to the Wade rules the cation of 2 has 20 valence electrons inside the clustercore. This leads to a structure very similar to closo-B9H92–.
