    (Cyanido-κC)(2,2-diphenylacetamido-κ2 N,O)bis(η5-pentamethylcyclopentadienyl)zirconium(IV)
    (Chester : International Union of Crystallography, 2014) Becker, L.; Spannenberg, A.; Arndt, P.; Rosenthal, U.
    In the title compound, [Zr(C10H15)2(C14H12NO)(CN)], the ZrIV atom is coordinated by two pentamethylcyclopentadienyl ligands, the amidate ligand via the N and O atoms, and an additional C N ligand. The four-membered metallacycle is nearly planar (r.m.s. deviation = 0.008Å). In the crystal, the molecules are connected into centrosymmetric dimers via pairs of N - HN hydrogen bonds.

    Bis(μ2-isopropylimido-κ2 N:N)bis[(η5-cyclopentadienyl)(ethenolato-κO)titanium(IV)]
    (Chester : International Union of Crystallography, 2014) Haehnel, M.; Spannenberg, A.; Rosenthal, U.
    The title dinuclear half-sandwich complex, [CpTi(OCH=CH2) (μ2-N-iPr)]2 (Cp = cyclopentadienyl; iPr = isopropyl), was obtained from the reaction of Cp2TiCl2, n-butyllithium and isopropylamine in tetrahydrofuran. Each TiIV atom is coordinated by one Cp ligand, one vinyloxy unit and two bridging imido groups in a strongly distorted tetrahedral geometry. There are two half molecules in the asymmetric unit, such that whole molecules being generated by inversion symmetry.

    (μ3-Hydrido)[μ3-2-(trimethylsilyl) ethylidyne-κ3C1:C1:C1] tetrakis[(η5-cyclopentadienyl)cobalt(II)]
    (Chester : International Union of Crystallography, 2013) Haehnel, M.; Spannenberg, A.; Rosenthal, U.
    In the title compound, [Co4(C5H5) 4(μ3-CCH2SiMe3)(μ3-H)], the Co atoms form a distorted tetrahedron with the ethylidyne moiety bridging three of the Co atoms as well as the hydrido ligand also bridging three of the Co atoms. The Co-Co bond lengths in the Co4tetrahedron vary from 2.3844 (4) to 2.4608 (4) Å. Each Co atom is additionally η5-bonded to a cyclopentadienyl (Cp) anion.
