The application of 1 H{ 31 P} and 1 H{ 103 Rh} double‐resonance techniques for the elucidation of the solution structure of the metalla‐tetrahedrane clusters of the [(triphos*)RhH 2 (AuPPh 3 ) 3 ][PF 6 ] 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 (AuPPh 3 ) 3 , mutual exchange of the diastereotopic hydrides and slow rotation of the RRS/SSR ‐triphos* unit in one diastereomer.
