Reactions of [Ru₃(CO)₁₂] with thiosaccharin (tsacH) at different temperatures have been investigated. At 40 °C, the diruthenium complex [Ru₂(CO)₆(μ-N,S-tsac)₂] (1) is produced and whose ruthenium atoms are bridged by two tsac ligands that are oriented in a head-tail fashion. When this reaction is carried out at 66 °C, the tri-, tetra- and penta-ruthenium complexes [H₂Ru₃(CO)₇(μ-N,S-tsac)(μ-C,N–C₆H₄CNSO₂)(μ₃-S)] (2), [Ru₄(CO)₁₂(μ-N,S-tsac)₂(μ₄-S)] (3) and [H₂Ru₅(CO)₁₃(μ-N,S-tsac)(μ-C,N–C₆H₄CNSO₂)(μ₃-S)(μ₄-S)] (4), respectively, were also isolated in addition to 1. The triruthenium complex 2 exhibits an arachno SRu₃ polyhedron containing edge-bridging tsac and C₆H₄CNSO₂ ligands. The tetraruthenium complex 3 consists of two [Ru₂(CO)₆(μ-N,S-tsac)] fragments linked via a μ₄-S ligand, while the pentaruthenium complex 4 is composed of individual Ru₃ and Ru₂ units linked via a μ₄-S ligand. At 81 °C, the same reaction furnishes the pentaruthenium complex [HRu₅(CO)₁₅(μ-N,S-tsac)(μ₅-S)] (5) containing tsac and μ₅-S bridging ligands. The molecular structures of the new complexes have been determined by single-crystal X-ray diffraction analyses, and the bonding in each product has been examined by DFT.
