A novel carbon dioxide complex: synthesis and crystal structure of [Nb(η-C5H4Me)2(CH2SiMe3)(η2-CO2)]

Garry S. Bristow,  Peter B. Hitchcock  and  Michael F. Lappert 

Abstract

Reduction of [Nb(η-C5H4Me)2(CH2SiMe3)Cl] with sodium amalgam in tetrahydrofuran under one atmosphere of carbon dioxide yields [Nb(η-C5H4Me)2(CH2SiMe3)(η2-CO2)](1), a moderately air-stable, thermally robust complex; the X-ray structure determination of complex (1) shows the distances Nb–CO2, Nb–OCO, C–ONb, and C[double bond, length as m-dash]O to be 2.144(7), 2.173(4), 1.283(8), and 1.216(8)Å, respectively, and ∠O–C–O 132.4(7)°.

    • For reproduction of material from PCCP:
      Reproduced from Ref. XX with permission from the PCCP Owner Societies.
    • For reproduction of material from PPS:
      Reproduced from Ref. XX with permission from the European Society for Photobiology, the European Photochemistry Association, and The Royal Society of Chemistry.
    • For reproduction of material from all other RSC journals and books:
      Reproduced from Ref. XX with permission from The Royal Society of Chemistry.

    If the material has been adapted instead of reproduced from the original RSC publication "Reproduced from" can be substituted with "Adapted from".

    In all cases the Ref. XX is the XXth reference in the list of references.
