“…Such replacement is associated with the ligand substitution at the iron site (eqn ( 5)) on the basis of the isolation of [Mo 3 (FeSPh)S 4 (dmpe) 3 Cl 3 ] (2) in analytically pure form under these experimental conditions (see below). All this evidence favours the interpretation that the first resolved kinetic step in the reaction of 1 with thiophenolate corresponds to the substitution of the Fe-coordinated chloride by PhSaccording to eqn (5). On the other hand, treatment of a brown CH 3 CN solution of 1 with a larger (six-fold) excess of PhScauses a progressive colour change from brown to red.…”

Selenium as a Structural Surrogate of Sulfur: Template-Assisted Assembly of Five Types of Tungsten–Iron–Sulfur/Selenium Clusters and the Structural Fate of Chalcogenide Reactants

et al. 2012

Syntheses of five types of tungsten-iron-sulfur/selenium clusters–incomplete cubanes, single cubanes, edge-bridged double cubanes (EBDCs), PN-type clusters, and double-cuboidal clusters–have been devised based on the concept of template-assisted assembly. The template reactant is six-coordinate [(Tp*)WVIS3]1−, which in the assembly systems organizes FeII,III and sulfide/selenide into cuboidal [(Tp*)WFe2S3] or cubane [(Tp*)WFe3S3Q] units. With appropriate terminal iron ligation, these units are capable of independent existence or may be transformed into higher nuclearity species. Selenide is used as a surrogate for sulfide in cluster assembly in order to determine by X-ray structures the position occupied by an external chalcogenide nucleophile or an internal chalcogenide atom in product clusters. Specific incorporation of selenide is demonstrated by formation of [WFe3S3Se]2+,3+ cubane cores. Reductive dimerization of the cubane leads to the EBDC core [W2Fe6S6Se2]2+ containing μ4-Se sites. Reaction of these species with HSe− affords the PN-type cores [W2Fe6S6Se3]1+ in which selenide occupies μ6-Se and μ2-Se sites. Reaction of [(Tp*)WS3]1−, FeCl2, and Na2Se results in the double cuboidal [W2Fe4S6Se3]2+,0 core with μ2-Se and μ4-Se bridges. It is highly probable that in analogous sulfide-only assembly systems, external and internal sulfide reactants occupy corresponding positions in cluster products. The results further demonstrate the viability of template-assisted cluster synthesis inasmuch as the reduced (Tp*)WS3 unit is present in all clusters. Structures, zero-field Mössbauer data, and redox potentials are presented for all cluster types. (Tp* = tris(pyrazolyl)hydroborate(1−))

“…Distinguishably, a new and strong diffraction peak located near 12° is presented in the pattern of the FeMoS NPs. As reported, various Mo–Fe–S clusters have been synthesized and structurally analyzed. − On the basis of the crystal data of these Mo–Fe–S clusters, their XRD patterns were simulated. As shown in Figure S1, the peaks of these Mo–Fe–S clusters are mainly located in the range 5–13°.…”

The selective adsorption by suitable substrate materials is considered one of the most economical methods. In this work, an all-inorganic bimetallic Mo-Fe-S cluster is facilely achieved through in situ chemical fixation of tetrathiomolybdate (TTM) on FeO nanoparticles (NPs) at room temperature (donated as FeMoS NPs). The bimetallic building blocks on the obtained FeMoS NPs possess a monovacancy species of sulfur, endowing FeMoS NPs with a selectivity order of Zn, Mn, Ni < Cd ≪ Cu < Pb for metal-ion adsorption, a novel application for the Mo-Fe-S clusters. Particularly, with the highest selectivity for Pb (K ≈ 10), which is about 3 × 10-1 × 10 times higher than those for other ions and has exceeded that of a series of outstanding sorbents reported for Pb, FeMoS NPs can efficiently reduce the concentration of Pb from ∼10 ppm to an extremely low level of ∼1 ppb. This facile and rational fabrication of the Mo-Fe-S cluster with FeO represents a feasible approach to cheaply develop novel and efficient materials for the selective removal of lead(II).
