Abstract:
A volume of 132 Å3 is enclosed by the title compound 1, which thus offers plenty of room for potential guest molecules. The synthesis from 2 [{Cp*RhCl2 }2 ] and 4 [CpCo(CN)3 ]- begins with the construction of a "molecular square" whose corners are alternately occupied by Co and Rh centers. Two squares react with one another to give a "molecular box" without cleavage of any M-C bonds. Cp=C5 H5 , Cp*=C5 Me5 .
