Résumé
Self-assembly of 2,4,6-tripyridyl-1,3,5-triazine (tpt) subunits with arene ruthenium building blocks and oxalato bridges affords cationic triangular metallo-prisms of the type [Ru<sub>6</sub> (arene) <sub>6</sub> (tpt)<sub>2</sub> (C<sub>2</sub>O<sub>4</sub>)<sub>3</sub>]<sup>6+</sup> (arene = C<sub>6</sub>Me<sub>6</sub> and <i>p</i>-Pr<sup><i>i</sup></i>C<sub>6</sub>H<sub>4</sub>Me); the unexpected double helical chirality of the metallo-prisms observed in the solid state persists in solution giving rise to two different stereodynamic processes as demonstrated by NMR enantiodifferentiation experiments.
