Abstract

A binuclear complex [(η⁶-p-cymene)₂Ru₂Cl₂(S₂POF)] (1) was generated by combining a binuclear ruthenium precursor [(η⁶-p-cymene)RuCl₂]₂ with an equivalent amount of [NⁿPr₄]₂[S₅P₂F₂] in dichloromethane at room temperature. Treatment of [(η⁶-p-cymene)RuCl₂]₂ with two equivalents of [NⁿPr₄]₂[S₅P₂F₂] in dichloromethane at reflux in the presence of AgNO₃ led to isolation of a binuclear ruthenium complex [(η⁶-p-cymene)Ru(S₂POF)]₂ (2). Complexes 1 and 2 were characterized by IR, multi-NMR (¹H, ³¹P, ¹⁹F) and UV–vis spectroscopies. The structures of complexes 1 and 2 have been established by single-crystal X-ray crystallography. In addition, the photocatalytic properties of complex 2 for hydrogen production from water splitting under visible light were also investigated.

两种双核硫桥聚伞烷-氟二硫代磷酸钌的合成、结构及光催化性能

以双核钌前体[（η - 6-p-花伞烯）RuCl2]2与等量的[NnPr4]2[S5P2F2]在室温下在二氯甲烷中合成双核配合物[（η - 6-p-花伞烯）2Ru2Cl2(S2POF)](1)。用[NnPr4]2[S5P2F2]两个等量物在AgNO3存在下回流二氯甲烷中处理[（η - 6-对伞花烃）RuCl2]2，分离得到双核钌配合物[（η - 6-对伞花烃）Ru(S2POF)]2(2)。配合物1和2通过IR，多核磁共振（1H, 31P, 19F）和紫外-可见光谱进行了表征。配合物1和2的结构已通过单晶x射线晶体学确定。此外，还研究了配合物2在可见光下对水裂解制氢的光催化性能。

期刊介绍： The Journal of Organometallic Chemistry targets original papers dealing with theoretical aspects, structural chemistry, synthesis, physical and chemical properties (including reaction mechanisms), and practical applications of organometallic compounds. Organometallic compounds are defined as compounds that contain metal - carbon bonds. The term metal includes all alkali and alkaline earth metals, all transition metals and the lanthanides and actinides in the Periodic Table. Metalloids including the elements in Group 13 and the heavier members of the Groups 14 - 16 are also included. The term chemistry includes syntheses, characterizations and reaction chemistry of all such compounds. Research reports based on use of organometallic complexes in bioorganometallic chemistry, medicine, material sciences, homogeneous catalysis and energy conversion are also welcome. The scope of the journal has been enlarged to encompass important research on organometallic complexes in bioorganometallic chemistry and material sciences, and of heavier main group elements in organometallic chemistry. The journal also publishes review articles, short communications and notes.
