One-pot galvanic formation of ultrathin-shell Sn/CoOx nanohollows as high performance anode materials in lithium ion batteries

The thermolysis of a heterobimetallic Sn-Co organometallic precursor resulted in the formation of hollow Sn/CoOx nanomaterials through galvanic reaction between metal species. The Sn/CoOx nanohollows with 6.1 nm diameter and ～1.5 nm shell thickness showed excellent lithium storage capacity of up to 857 mA h g-1 after 30 cycles.

Oxidation products of vanadocene and of its permethylated analogue, including the isolation and the reactivity of the unsolvated [VCp2]+ cation

The one-electron oxidation of vanadocene, VCp2, by [FeCp2]+ in toluene affords the 14-electron [VCp2]+ cation, which has been isolated as an unsolvated species for the first time. Vanadium hexacarbonyl reacts with VCp2 to give the μ-isocarbonyl derivative Cp2V(μ-OC)V-(CO)5 as a transient species, which has been characterized in solution by IR analysis. By reaction of VCp2 with V(13CO)6 followed by treatment with 12CO, the ionic dicarbonyl derivative [VCp2(12CO)2][V(13CO)6] is formed, thus showing that during the formation of the ionic compound no redistribution of the carbonyl ligands between the two metal centers occurs. Bis(cyclopentadienyl)vanadium(II) and Co2(CO)8 give Cp2VCo(CO)4, which slowly decomposes in solution even at low temperature to give [VCp2(CO)2][Co(CO)4], which was identified by conventional methods, including single-crystal X-ray diffraction. The reactivity of the unsolvated [VCp2]+ cation as well as that of the heterobimetallic compound containing vanadium and cobalt with several Lewis bases is reported.

Coordination chemistry of group 14 metalloles. 5. Use of dicarbonyl (η5-cyclopentadienyl) (1-methyl-2,5-diphenyl-silacyclopentadien-1-yl)iron as a four-electron ligand: Chemical properties and dynamic stereochemistry of the complexes

Chlorine is displaced in 1-chloro-1-methyl-2,5-diphenylsilole by dicarbonyl(η5-cyclopentadienyl)ferrate(I) to give a silole with a Si-Fe σ bond. Attempts to displace the carbonyl ligands to give the corresponding silaferrocene were unsuccessful. This new silole behaves as an efficient η4-ligand with transition metals, giving a new series of complexes which present an interesting reactivity. Thus the Si-Fe bond can be cleaved without decoordination of the η4-ligand, and the Co-Co bond in (CO)6(η4-silole)Co2 can be cleaved without cleavage of the Fe-Si bond. These η4-complexes are fluxional as observed for other series. The interconversion, in solution, of the two enantiomers cis-Δuu and cis-Λuu has an activation energy of ～35 kJ mol-1 and a coalescence temperature of ～ 200 K. However, contrary to other cases, the presence of diastereoisomers cannot be detected.

The reactions of 1,4-dilithio-1,4-diphenylbutadiene with several di- and trichloro- (or trimethoxy-) silanes lead to the formation of the corresponding silicon-substituted 2,5-diphenylsilacyclopentadienes. The compounds thus obtained are 1 (H, Cl), 2 (Me,

REDUCTIONS OF METAL CARBONYLS BY QUATERNARY AMMONIUM BOROHYDRIDES

Quaternary ammonium borohydrides, used directly or generated in phase transfer reactions, are highly effective reagents for preparing metal carbonyl anions from metal carbonyls 5-C5H5)2Mo2(CO)6> and from some metal carbonyl halides 5-C5H5Mo(CO)3Cl>.Where strongly basic anions would be fromed from a halide 5-C5H5Ru(CO)2Br>, the reactions provide efficient syntheses of the corresponding hydrides instead.The anion η5-C5H5Fe(CO)2- is not accessible bythese techniques; reaction of η5-C5H5Fe(CO)2Br yields the iron dimer (via the highly nucleophilic anion) and the dimer is unreactive toward Q+BH4-.Reductions of Re2(CO)10 conducted in CH2Cl2 provide Re2(CO)9Cl- in high yield.

Organometallic compounds with metal-metal bonds. VII. Preparation and a study of the infrared spectra of mono- and bis(tetracarbonylcobalt) derivatives of germanium and tin

Infrared spectra in the carbonyl stretching region are reported and discussed for a large number of mono- and bis(tetracarbonylcobalt) derivatives of germanium and tin, most of which are new compounds. The monocobalt derivatives are of the types XnR3-nGeCo(CO)4 (X = Cl, Br, I; R = CH3, C6H5), X3SnCo(CO)4 (X = Cl, I), R3SnCo(CO)4 (R = CH3, C6H5), and (C6H5)3PbCo(CO)4. Assignments are proposed for the three or four terminal stretching bands; a linear increase in frequency of the A1 modes with electronegativity of substituents on germanium or tin is noted. The biscobalt derivatives are of the type XnR2-nM[Co(CO)4]2 (M = Ge, Sn), and two of the seven or eight observed carbonyl bands are tentatively assigned. Nmr spectra are reported for the methyltin derivatives. The compounds are moderately stable in the absence of air, and most are prepared by reaction of Co(CO)4- with halides or organometallic halides of germanium or tin.
