Abstract

The clusters (μ-H)Ru₃M(μ₄-η²-COMe)(CO)₁₂ (M = Ru, Fe) have been prepared and characterized by single-crystal X-ray diffraction techniques. Also prepared were (μ-H)Ru₃-Fe(μ₄-η²-CNMe₂)(CO)12 (lowyield) and (μ-H)Ru₄(μ₃-COMe)(CO)₉{(PPh₂)₃CH}, both characterized by spectroscopic methods. The isomorphous complexes (μ-H)Ru₃M(μ₄-η²-COMe)(CO)₁₂ (M = Ru, Fe) crystallize in the centrosymmetric space group P2₁/c. Unit cell parameters for the tetraruthenium complex are a = 9.277 (2) Å, b = 9.441 (1) Å, c = 25.041 (3) Å, ² = 92.53 (1)°, V = 2191.2 (5) Å³, and Z = 4; for the triruthenium-iron complex they are a = 9.188 (1) Å, b = 9.433 (1) Å, c = 24.820 (3) Å,β = 91.50 (1)°, V = 2150.5 (4) Å³, and Z = 4. The complexes each contain a tetranuclear cluster of metal atoms in a butterfly configuration. The iron atom in the Ru₃Fe species occupies a “wing-tip” position. Each complex contains three terminal carbonyl ligands linked to each metal atom, a μ-hydride ligand bridging the “bridgehead” metal atoms, and a complex μ₄-η²-COMe ligand in which the alkylidyne carbon atom interacts with all four metal atoms and the oxygen atom is linked to one wing-tip ruthenium atom.
