Resumen

The tetranuclear ruthenium clusters [Ru₄(CO)₆(μ-CO)₃(μ₄-S) ₂{C(NHR)₂}₂] 1 (R = Prⁱ) and 3 (R = Et) and [Ru₄(CO)₇(μ-CO)₃(μ₄-S) ₂{C(NHR)₂}] 2 (R = Prⁱ) and 4 (R = Et) were obtained from the thermal reaction of [Ru₃(CO)₁₂] with thioureas SC(NHR)₂ (R = Prⁱ or Et). In the case of diethylthiourea, a trinuclear cluster [Ru₃(μ-H)(CO)₉(μ₃-NEtCSNHEt)] 5 was isolated in addition to 3 and 4. The single-crystal X-ray structure analyses of 1 and 2 reveal a pseudo-octahedral Ru₄S₂ skeleton with three μ-carbonyl bridges in the Ru₄ plane; 1 has two terminal diaminocarbene ligands and six terminal carbonyls, whereas there is only one terminal diaminocarbene ligand but seven terminal carbonyls in 2.
