Abstract

A cluster-ligand is disclosed in the form of [Ru₃(CN)₃(CO)₉]³⁻ ([1]³⁻). Produced by simple reaction of [Ru₃(CO)₁₂] with cyanide, [1]³⁻ serves as a precursor to a series of μ-CN cages. When treated with [Ru₃(CO)₁₂], it readily forms the prism [Ru₆(μ-CN)₃(CO)₁₈]³⁻. With 1.5 equiv. of [Cu(MeCN)₄]⁺ [1]³⁻ reacts to give the expanded prism {Cu₃[Ru₃(μ-CN)₃(CO)₉]₂}³⁻, which features three two-coordinate Cu(I) centers. Sources of Ni²⁺ and Fe²⁺ bind two equivalents of [1]³⁻, giving the double cages {M[Ru₃(μ-CN)₃(CO)₉]₂}⁴⁻ (M=Ni, Fe) wherein the central metal is octahedral. The 1 : 1 reaction using [Fe(H₂O)₆]²⁺ gave the interpenetrated super-tetrahedrane {Fe₄(μ₄-O)[Ru₃(μ-CN)₃(CO)₉]₄}⁴⁻.
