Encapsulation of Triphenylene Derivatives in the Hexanuclear Arene Ruthenium Metallo-Prismatic Cage [Ru6 (p-PriC6H4Me)6(tpt)2 (dhbq)3]6+ (tpt = 2,4,6-tri(pyridin-4-yl)-1,3,5-triazine, dhbq = 2,5-dihydroxy-1,4-benzoquinonato)

A large cationic triangular metallo-prism, [Ru6(p-PriC6H4Me)6 (tpt)2 (dhbq)3]6+ (1)6+, incorporating p-cymene ruthenium building blocks, bridged by 2,5-dihydroxy-1,4-benzoquinonato (dhbq) ligands, and connected by two 2,4,6-tri(pyridin-4-yl)-1,3,5-triazine (tpt) subunits, allows the permanent encapsulation of the triphenylene derivatives hexahydroxytriphenylene, C18H6 (OH)6 and hexamethoxytriphenylene, C18H6 (OMe)6. These two cationic carceplex systems [C18H6 (OH)6⊂1]6+ and [C18H6 (OMe)6⊂1]6+ have been isolated as their triflate salts. The molecular structure of these systems has been established by one-dimensional 1H ROESY NMR experiments as well as by the single-crystal structure analysis of [C18H6 (OMe)6⊂1][O3SCF3]6.
