Abstract

The reactions of activated tetraosmium carbonyl cluster [Os4(μ-H)4(CO)11(NCMe)] 1 with monopyridyl ligands give new clusters [Os4(μ-H)4(CO)11(pyp)] 3 and [Os4(μ-H)4(CO)11(pya)] 4. Similarly, the reactions of [Os4(μ-H)4(CO)10(NCMe)2] 2 with bipyridyl or phenanthroline type ligands afford [Os4(μ-H)4(CO)10(bpy)] 5, [Os4(μ-H)4(CO)10(dpbpy)] 6, [Os4(μ-H)4(CO)10(phen)] 7, [Os4(μ-H)4(CO)10(dmdpp)] 8, and [Os4(μ-H)4(CO)10(dppz)] 9, which exhibit interesting ring conformations. Treatment of 2 with nitrogen-phosphorus mixed donor ligand gives a novel bridging cluster [Os4(μ-H)4(CO)10(dpppy)] 10.
