Abstract: | B3N3Me6Cr(CO)3 reacts with [AsPh4] [SnCl3] and [AsPh4] [GeCl3] in tetrahydrofuran to give [AsPh4]3[Cr(CO)3(SnCl3)3] and [AsPh4]3[Cr(CO)3(GeCl3)3], respectively. According to IR. and 13C-NMR.-data, the tricarbonylate anions possess a meridional configuration. The donor-acceptor properties of SnCl3? and GeCl3? in the anions [Cr(CO)3(ECl3)3]3? (E = Sn, Ge) are very similar. A similar synthesis of [AsPh4]3[Cr(CO)3(SnF3)3] was not successful. |
