2006_13/2006Triple-Decker Transition-Metal Complexes (CnHn)M(B6C)M(CnHn) (M = Fe, Ru, Mn, Re; n = 5, 6) Containing Planar Hexacoordinate Carbon Atoms (Eur. J. Inorg. Chem. 13/2006)

The cover picture shows the structure and IR spectrum of a novel triple-decker complex (C5H5)Fe(B6C)Fe(C5H5) obtained by density functional calculations. Similar results on a series of (CnHn)M(B6X)M(CnHn) (M = Fe, Ru, Mn, Re; X = B, C, N; n = 5, 6) complexes containing planar hexacoordinate carbon or other nonmetal atoms at the centers of the B6X middle-deckers were also obtained. Natural orbital analyses indicate that the nonmetal centers X follow the octet rule in these complexes, and effective d–π coordination interactions exist between the partially filled Fe 3d orbitals and the delocalized π orbitals of the three parallel ligands. This work provides strong theoretical evidence to facilitate future experimental characterization of the long-sought planar hexacoordinate carbon atom and expands the structural domain of traditional sandwich-type transition-metal complexes. Details are discussed in the article by S.-D. Li et al. on p. 2567 ff.
