Abstract

In this article, six new Fe₃S₂ cluster complexes Fe₃(µ₃S)₂(CO)₇[(Ph₂P)₂NR] (1-6) (R = (CH₂)₂CH₃, CH(CH₃)₂, (CH₂)₃CH₃, CH₂CH(CH₃)₂, p-C₆H₄CCH and m-C₆H₄CCH) were successfully synthesized by reactions of Fe₃S₂(CO)₉ and the corresponding aminodiphosphines under refluxing toluene. Meanwhile, treatment of Fe₃S₂(CO)₉ and (Ph₂P)₂NCH(CH₃)Ph afforded two new Fe₃S₂ cluster complexes Fe₃(µ₃-S)₂(CO)₇[(Ph₂P)₂NCH(CH₃)Ph] (7) and Fe₃(µ₃-S)₂(CO)₇[(κ²-Ph₂P)₂NCH(CH₃)(Ph)] (8). Complexes 1–8 were characterized by elemental analysis, FT-IR, NMR spectroscopy, and especially X-ray crystallography. The elctrochemical properties were investigated by cyclic voltammetry, showing that they all have electrocatalytic ability for the reduction of protons to H₂.

期刊介绍： The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science. Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
