The molecular structure of complex 1 has been determined by X-ray diffraction methods. The tetranuclear structure is supported by two S,N,O-tridentate ligands exhibiting a 1κO, 2κN, 3:4κ2S coordination mode. Carbonylation of the rhodium diolefin complexes at atmosphericpressure gives [Rh4(μ-PySO)2(CO)8] (4). The carbonylation of 1 is partially reversible, and the mixed-ligand complex [Rh4(μ-PySO)2(cod)2(CO)4]
