- Item[1-Dimethylsilyl-2-phenyl-3-(η5-tetramethylcyclopentadienyl) prop-1-en-1-ylκC1](n5-pentamethylcyclopentadienyl)- titanium(III)(Chester : International Union of Crystallography, 2009) Lamač, M.; Spannenberg, A.; Arndt, P.; Rosenthal, U.The title compound, [Ti(C10H15)(C20H 26Si)], was obtained from the reaction of [Ti{5: 1-C5Me4(CH2)}(5-C 5Me5)] with the alkynylsilane PhC2SiMe 2H. The complex crystallizes with two independent mol-ecules in the asymmetric unit, which differ in the conformation of the propenyl unit, resulting in their having opposite helicity. No inter-molecular inter-actions or inter-actions involving the Si- H bond are present. The observed geometrical parameters are unexceptional compared to known structures of the same type.
- Item(μ5-Cyclo-penta-dien-yl)bis-(triphenyl-phosphane)cobalt(I) -toluene-n-hexane (1/0.20/0.25)(Chester : International Union of Crystallography, 2008) Hapke, M.; Spannenberg, A.The title compound, [Co(C5H5)(C18H15P)2]·0.2C7H8·0.25C6H14, was synthesized by the reaction of cobaltocene, Cp2Co, with elemental lithium in tetra-hydro-furan in the presence of two equivalents of PPh3. The mol-ecular structure displays a cobalt(I) center in a distorted trigonal-planar coordination environment, with one Cp and two phosphane ligands. There are two crystallographically independent mol-ecules in the asymmetric unit besides the disordered solvent molecules.
- ItemP-[N-(Diphenyl-phospho-rothio-yl)iso-propyl-amino]-N-isopropyl-P-phenyl- thio-phosphinic amide(Chester : International Union of Crystallography, 2009) Peulecke, N.; Aluri, B.R.; Wöhl, A.; Spannenberg, A.; Al-Hazmi, M.H.The title compound, C24H30N2P2S2, was obtained by the reaction of Ph2PN(iPr)P(Ph)N(iPr)H with elemental sulfur in tetra-hydro-furan. In the solid state, intra-molecular N - H⋯S hydrogen bonding influences the mol-ecular conformation; a P - N - P - N torsion angle of 2.28 (9)° is observed. The two phenyl rings attached to one P atom form a dihedral angle of 74.02 (4)°.
- ItemBis[N,N′-bis-(2,6-diisopropylphenyl)ethane-1,2-diimine] -1κ2 N,N′;2κ2 N,N′-tri - Trichlorido-1:2κ6 Cl:Clchlorido-1Cltetrahydrofuran- 2Odichromium(II) dichloromethane 4.5-solvate(Chester : International Union of Crystallography, 2009) Peitz, S.; Peulecke, N.; Müller, B.H.; Spannenberg, A.; Rosenthal, U.In the mol-ecular structure of the title compound, [Cr2Cl4(C 26H36N2)2(C4H8O)] ·4.5CH2Cl2, the two CrII centers are bridged by three Cl atoms, forming a dinuclear complex. Each CrII center is coordinated by one chelating bis-(2,6-diisopropyl-phen-yl)ethane-1,2-diimine ligand via both N atoms. An additional chloride ion binds to one chromium center, whereas an additional tetra-hydro-furan mol-ecule coordinates to the second CrII center. The coordination geometry at each CrII center can be best described as distorted octa-hedral.
- Item1,1,2,2-Tetra-phenyl-15-diphosphane 1-sulfide(Chester : International Union of Crystallography, 2009) Aluri, B.R.; Peitz, S.; Wöhl, A.; Peulecke, N.; Müller, B.H.; Spannenberg, A.; Rosenthal, U.In the title mol-ecule, C24H20P2S, the P - P bond length is 2.2263 (5) Å. The two phenyl rings attached to the three- and five-coordinated P atoms, respectively, form dihedral angles of 56.22 (5) and 71.74 (5)°.
- ItemDiacetonitrile[N,N′-bis(2,6-diisopropyl-phenyl)ethane-1,2-diimine] dichloridochromium(II) acetonitrile solvate(Chester : International Union of Crystallography, 2009) Peitz, S.; Peulecke, N.; Müller, B.H.; Spannenberg, A.; Rosenthal, U.The title compound, [CrCl2(CH3CN)2(C 26H36N2)]·CH3CN, was synthesized by the reaction of CrCl2(THF)2 with N,N′-bis-(2,6- diisopropyl-phen-yl)ethane-1,2-diimine in dichloro-methane/acetonitrile. The chromium center is coordinated by two N atoms of the chelating diimine ligand, two chloride ions in a trans configuration with respect to each other, and by two N atoms of two acetonitrile mol-ecules in a distorted octa-hedral geometry.
