Notes:
The application of 1H{31P} and 1H{103Rh} double-resonance techniques for the elucidation of the solution structure of the metalla-tetrahedrane clusters of the [(triphos*)RhH2(AuPPh3)3][PF6]2 type, with the chiral tripodal phosphine triphos* [RRR/SSS- or RRS/SSR-1,1,1,-tris(methylphenylphosphinomethyl)ethane] is described. Variable-temperature studies revealed three types of dynamic processes, i.e. rapid rotation of the trigold moiety (AuPPh3)3, mutual exchange of the diastereotopic hydrides and slow rotation of the RRS/SSR-triphos* unit in one diastereomer.
