Low-Valent M_x Al₃ Cluster Salts with Tetrahedral [SiAl₃ ]⁺ and Trigonal-Bipyramidal [M₂ Al₃ ]²⁺ Cores (M=Si/Ge).

ABSTRACT: Schnöckel's [(AlCp*)₄ ] and Jutzi's [SiCp*][B(C₆ F₅ )₄ ] (Cp*=C₅ Me₅ ) are landmarks in modern main-group chemistry with diverse applications in synthesis and catalysis. Despite the isoelectronic relationship between the AlCp* and the [SiCp*]⁺ fragments, their mutual reactivity is hitherto unknown. Here, we report on their reaction giving the complex salts [Cp*Si(AlCp*)₃ ][WCA] ([WCA]^- =[Al(OR^F )₄ ]^- and [F{Al(OR^F )₃ }₂ ]^- ; R^F =C(CF₃ )₃ ). The tetrahedral [SiAl₃ ]⁺ core not only represents a rare example of a low-valent silicon-doped aluminium-cluster, but also-
