Abstract

In acetonitrile solvent, Fe5(CO)155- C), 1, reacts with Ni(COD)2 at room temperature to afford the iron-nickel complex Fe5NI(NCMe)(CO)156-C), 3. The acetonitrile ligand In 3 can be replaced by CO and NH3 to yield Fe5Ni(CO)166-C), 4, and Fe 5Ni(NH3)(CO)156-C), 6, respectively. When refluxed In acetonitrile solvent, compound 3 loses a vertex to form the square pyramidal Fe4Ni complex Fe4Ni(NCMe) 2(CO)125-C), 7. Compound 7 readily converts to Fe4Ni(NCMe)(CO)135-C), 8, by losing one of Its acetonitrile ligands. Addition of acetonitrile to 8 gives compound 7. When heated to 110 o°C under an atmosphere of CO, both compounds 7 and 8 furnish the octahedral Fe4NI2 complex Fe 4Ni2(CO)156-C), 9. All six compounds were structurally characterized by single-crystal X-ray diffraction analyses.
