Diastereomeric separation of [{M(Cp*)(ado)}(3)](3+) (M = Rh-III, Ir-III; ado = adenosinato): crystal structure of an inclusion compound [{Rh(Cp*)(ado)}(3)](CF3SO3)(3)center dot MeOH

A diastereomer with a C-3 cyclic trimer [{Rh(adenosine)(Cp*)}(3)](CF3SO3)(3), which was obtained selectively by a second-order asymmetric transformation, can include one methanol molecule into its triangle dome-like cavity.
