Structure and electronic properties of [Ni(dsdm){Fe(CO)3}2], an unusual, triangular nickel diiron compound

Academic Article

Abstract

  • Reaction of the low-spin complex [Ni(dsdm)] with Fe2CO9 results in the unique trinuclear cluster [Ni(dsdm){Fe(CO)3}2]. NMR spectroscopy shows that the structure is diamagnetic, and, moreover, that the complex is stable in solution and C2-symmetric. The X-ray structure reveals short distances between the distorted octahedral nickel(11) ion and the two octahedral iron(0) centers. The observed diamagnetism is explained by the formation of a triangular metal core with three two-electron two-center bonds. The M√∂ssbauer spectra, which are typical of iron(0), are composed of asymmetric quadrupole doublets as a result of the presence of two chemically similar, but crystallographically distinct, iron sites. ¬© Wiley-VCH Verlag GmbH & Co.
