Characterization of Incomplete Cubane-Type and Cubane-Type Sulfur-Bridged Clusters

“…Similar chemistry of dinuclear sulfur-bridged iron (30) and vanadium (31) compounds has also been reported. No report has appeared on the reaction of trinuclear metal clusters with acetylene or acetylenederivatives to form carbon-bridging-sulfur bonds.…”

A Vanadium-Containing Iron−Sulfur Cluster with a V2Fe2S4 Cubane-like Core. Synthesis, Structure, and Characterization of (Et4N)[V2Fe2S4(Me2dtc)5]

“…containing a V-V single bond, such as (i-PrCp) 2 V 2 S 4 (2.610-(1) Å), 21 V 2 (S 2 ) 2 (S 2 CMe) 4 (2.800(2) Å), 22 [V 2 (S 2 ) 2 (CS 3 ) 4 ] 4-(2.872(6) Å), 23 V 2 (S 2 ) 2 (i-Bu 2 dtc) 4 (2.851 Å), 5 and V 2 (S 2 ) 2 (Et 2dtc) 4 (2.884(4) Å). 24 The V-Fe distances, being the third type of M-M bond in the cubane cluster, have a mean distance of 2.780(6) Å, which is slightly longer than those in several V /Fe/S compounds.…”

Carbon—Sulfur Bond Cleavage of Thiolates on Electron-Deficient Transition Metals

“…From the analogous Cp*MoCl4/Li 2 (SCH 2 CH 2 CH 2 S) reaction system in THF, a dark (15). The structure of the anion part of 15 consists of three Cp*Mo(SCH2CH2CH2S)2 units linked by three lithium cations at sulfurs of the thiolates, and the lithium cations are bound to the CI anion which sits at the center of the cluster molecule (Scheme 8).…”

“…The μ-S ligands in (C5H5)2Mo2^-S)2^-SH) 2 (14) and (C5H4Me)2V2^-S)2(n-S2) (15) were reported to react with HCsCH and CF3C=CCF3, respectively, and recentiy various alkynes were found to add to the μ-bridging thio ligands in [Μθ3(μ3-8)(μ-0)(μ-8)2(Η2θ)9]*+ (16). Even more scarce is the reaction of terminal monothio ligands, and the single example reported so far is the formation of a 1,2-enedithiolate by addition of DMAC to {HB(Me2pz)3}WS2X (X = OPh, SPh, SePh) (17).…”
