Abstract

The hydrogenase model [Fe₂(S₂C₃H₆)(CN)₂(CO)₄]^2- was employed as a molecular tecton for the construction of supramolecular aggregates. IR spectroscopy indicated that cyanide bridged aggregates are formed when [Fe₂(S₂C₃H₆)(CN)₂(CO)₄]^2- was treated with Lewis acids such as Zn(tetraphenylporphyrinate), [Cu(NCMe)(2,2′-bipyridine)]PF₆ and [Cu(NCMe)₄]PF₆. Condensation of [Fe₂(S₂C₃H₆)(CN)₂(CO)₄]^2- with the tritopic Lewis acid [Cp^*Rh]²⁺ afforded the novel expanded tetrahedron cage, {[Fe₂(S₂C₃H₆)(CN)₂(CO)₄]₆[Cp^*Rh]₄}^4-. The tetrahedron cage was characterized crystallographically as the PPN salt.
