Ds. Shephard et al., NOVEL REDOX-ACTIVE RUTHENIUM CLUSTER CROWN COMPOUNDS CAPABLE OF HOST-GUEST CHEMISTRY, Journal of the Chemical Society. Dalton transactions, (14), 1998, pp. 2289-2291
The new redox-active cluster compounds [Ru6C(CO)(14)(eta(6)-C6H4C8H16O
5)] and [Ru6C(CO)(14)(eta(6)-C6H4C10H20O6)] have been synthesised by d
irect reaction of the aryl crown ether with the hexaruthenium carbido
cluster [Ru6C(CO)(17)] and display host-guest type behaviour with cati
ons Na+ and NH4+ both spectroscopically and electrochemically.
