摘要

While the room temperature reaction of [RuCl2(CO)(3)](2) and Ph2S in tetrahydrofuran in air affords [RuCl2(CO)(2)(SPh2)(2)] (1) in moderate yield, that in dichloromethane results in the formation of a mixture of [RuCl2(CO)(3)(H2O)] (2) and [Ru(H2O)(6)][RuCl3(CO)(3)](2).2H(2)O (3). Very small amounts of 1 are produced only upon prolonged reflux of the reagents. All compounds were characterized by X-ray crystallography. 1 crystallizes as discrete octahedral cis(CO), cis(Cl), trans(Ph2S) complexes, which are joined into stacks by weak H...Cl hydrogen bonds. 2 is also composed of discrete octahedral complexes. Four hydrogen bonds involving aqua and chlorido ligands link two complexes into a dimer. The structure of 3 consists of octahedral hexaaquaruthenium cations and two tricarbonyl-trichloridoruthenate anions. The water of crystallization is involved in hydrogen bonding between the cations and anions resulting in the formation of a continuous three-dimensional network. [References: 12]
