  Effects of Main-Group and Transition Elements on Bond Formation and Cleavage in Transition-Metal Chalcogenide Clusters: Reactions of E2Fe3(CO)9 (E = Te, Se) with [Co(CO)4]-, [Mn(CO)5]-, and [Fe(CO)4]2-

  摘要：

  The tetrahedral clusters [EFe(2)Co(CO)(9)](-)(E=Te, I; E=Se, II) were synthesized by reactions of the isostructural complexes E(2)Fe(3)(CO)(9) with [Co(CO)(4)](-), respectively. Reaction of Te2Fe3(CO)(9) with [Mn(CO)(5)](-) gives a Mn(CO)(4) bridging butterfly [Te2Fe2Mn(CO)(10)](-)(III), while treatment of Se2Fe3(CO)(9) with [Mn(CO)(5)](-) produces a square-pyramidal [Se2Fe2Mn(CO)(9)](-)(IV). When Te2Fe3(CO)(9) reacts with Collman's reagent, [Fe(CO)(4)](2-) the previously characterized [Te6Fe8(CO)(24)](2-) is formed. The similar reaction of Se2Fe3(CO)(9) with [Fe(CO)(4)](2-) generates the known complexes [SeFe3(CO)(9)](2-) and [HSeFe3(CO)(9)](-). The anionic complexes I-IV are fully characterized by infrared spectroscopy, elemental analysis, negative-ion mass, or/and X-ray diffraction methods. Crystals of [Et(4)N]-[II] are tetragonal, space group P4(2)/ncm with a=16.456(3) Angstrom, c=17.925(6) Angstrom, V=4854(2) Angstrom(3), Z=8; R=0.045, and R(w)=0.051 at 25 degrees C. [Et(4)N][III] crystallizes in the triclinic space group P $($) over bar$$ 1 with a=9.343(3) Angstrom, b=12.401(6) Angstrom, c=13.198(2) Angstrom, alpha=77.96(3)degrees, beta=74.36(2)degrees, gamma=69.72(3)degrees, V=1370(1) Angstrom(3), Z=2, R=0.026, and R(w)=0.028 at 25 degrees C. Crystals of [Et(4)N][IV] are monoclinic, space group P2(l)/n with a=9.236(2) Angstrom, b=24.665(6) Angstrom, c=11.870(1) Angstrom, beta=112.62(2)degrees, V=2496(1) Angstrom(3), Z=4, R=0.032, and R(w)=0.039 at 25 degrees C. This paper describes the similarities and differences among these reactions and discusses the effects of the main-group and transition elements on bond formation and cleavage of transition-metal chalcogenide clusters.

  Interfacial Electron Transfer to the Zeolite-Encapsulated Methylviologen Acceptor from Various Carbonylmanganate Donors. Shape Selectivity of Cations in Mediating Electron Conduction through the Zeolite Framework

  摘要：

  The series of (one-electron) reductions of methylviologen (MV(2+)) intercalated into zeolite-Y by various carbonylmanganate donors [C+Mn(CO)(4)L(-), L = CO, P(OPh)(3)] are very selective and highly dependent on the size/ shape of the counterion C+, although the same electron transfers carried out (homogeneously) in solution always occur spontaneously, irregardless of C+. For example, the complete reduction of MV(2+) extensively doped into zeolite-Y proceeds rapidly and quantitatively when the Na+ salts of the carbonylmanganates are employed as the reductants, but only to a very limited extent (1%) when the large PPN+ [bis(triphenylphosphine)iminium] salts of the carbonylmanganates are employed. The medium-size tetraethylammonium (TEA(+)) salt of Mn(CO)(4)P(OPh)(3)(-) slowly effects an intermediate conversion (80%). Based on the fact that the large phosphite-substituted Mn(CO)(4)P(OPh)(3)(-) donor cannot enter the supercage of zeolite-Y, we propose interfacial electron transfer from the carbonylmanganate to the MV(2+) acceptor to occur only at the zeolite periphery. Importantly, the strong dependence of the further progress of the redox reaction with decreasing size of the cation C+ (i.e., shape selectivity) predicts that electron conduction throughout the zeolite framework requires the simultaneous transport of these cations in order to effect the complete reduction of all the encapsulated MV(2+), as presented in Chart 5.

Where strongly basic anions would be formed from a halide [BrMn(CO)4PPh3 and η5-C5H5Ru(CO)2Br], the reactions provide efficient syntheses of the corresponding hydrides instead. The anion
