- Item2-hydroxyethylammonium iodide(Chester : International Union of Crystallography, 2014) Kohrt, C.; Spannenberg, A.; Werner, T.In the crystal structure of the title salt, C2H 8NO+·I-, N-H⋯O, N-H⋯I and O-H⋯I hydrogen bonds lead to the formation of layers staggered along the c axis.
- ItemTris(η5-cyclopentadienyl)hafnium(III)(Chester : International Union of Crystallography, 2011) Burlakov, V.V.; Arndt, P.; Spannenberg, A.; Rosenthal, U.In the crystal structure of the title compound, [Hf(C5H 5)3], three cyclopentadienyl ligands surround the Hf III atom in a trigonal-planar geometry. The molecule lies on a sixfold inversion axis.
- Item{N,N-Bis[bis(2,2,2-trifluoroethoxy)phosphanyl]methylamine- κ2 P,P′}bis(η5-cyclopentadienyl) titanium(II)(Chester : International Union of Crystallography, 2013) Haehnel, M.; Hansen, S.; Spannenberg, A.; Beweries, T.The title compound, [Ti(C5H5)2(C 9H11F12NO4P2)], is a four-membered titanacycle obtained from the reaction of Cp2Ti(η 2-Me3SiC2SiMe3) and CH 3N[P(OCH2CF3)2]2 {N,N-bis[bis(trifluoroethoxy)phosphanyl]methylamine, tfepma}. The Ti II atom is coordinated by two cyclopentadienyl (Cp) ligands and the chelating tfepma ligand in a strongly distorted tetrahedral geometry. The molecule is located on a mirror plane.
- ItemDicarbonyl-{3,3′-di-tert-butyl-5,5′-di-methoxy-2, 2′-bis[(4,4,5,5-tetraphenyl-1,3,2-dioxaphospho-lan-2-yl)-oxy-κP] biphen-yl}hydridorhodium(I) diethyl ether monosolvate(Chester : International Union of Crystallography, 2012) Selent, D.; Spannenberg, A.; Börner, A.In the title compound, [Rh(C 74H 68O 8P2)H(CO) 2]·C 4H 10O, the C 2HP 2 coordination set at the Rh I ion is arranged in a distorted trigonal-planar geometry with one P atom of the diphosphite mol-ecule and the H atom adopting the axial coordination sites.
- ItemEthyl 4-chloro-2′-fluoro-3-hydroxy-5-methylbiphenyl-2-carboxylate(Chester : International Union of Crystallography, 2011) Adeel, M.; Langer, P.; Villinger, A.In the title compound, C 16H 14ClFO 3, the dihedral angle between the mean planes of the two benzene rings is 71.50 (5)°. Due to an intramolecular O - H⋯O hydrogen bond between the hydroxy group and the carbonyl O atom of the ethyl ester group, the ethyl ester group lies within the ring plane. The crystal structure is consolidated by intermolecular C - H⋯O and C - H⋯F interactions.
- Item(Isopropyl-amino)(meth-yl)diphenyl-phospho-nium iodide(Chester : International Union of Crystallography, 2011) Peulecke, N.; Peitz, S.; Müller, B.H.; Spannenberg, A.; Rosenthal, U.The title compound, C 16H 21NP +· I -, was obtained by the reaction of PH 2PN( iPr)P(Ph)N( iPr)H with MeI involving cleavage of one of the P - N bonds in diethyl ether. The two phenyl rings form a dihedral angle of 82.98 (5)°. A weak donor-acceptor N - H⋯I inter-action is observed.
- ItemBis(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.
- ItemCarbonyl{3,3′-di-tert-butyl-5,5′-dimethoxy-2,2′-bis[(4,4, 5,5-tetramethyl-1,3,2-dioxaphospholan-2-yl)oxy]biphenyl-κ2 P,P′}hydrido(triphenylphosphane-κP)rhodium(I) diethyl ether trisolvate(Chester : International Union of Crystallography, 2013) Selent, D.; Spannenberg, A.; Börner, A.In the title compound, [RhH(C74H68O8P2)(C18H15P)(CO)]·3C4H10O, the CHP3 coordination set at the RhI ion is arranged in a distorted trigonal-bipyramidal geometry with the P atoms adopting equatorial coordination sites and the C atom of the carbonyl ligand as well as the H atom adopting the axial sites. The asymmetric unit contains two very similar molecules of the rhodium complex, two half-occupied diethyl ether molecules and further diethyl ether solvent molecules which could not be modelled successfully. Therefore contributions of the latter were removed from the diffraction data using the SQUEEZE procedure in PLATON [Spek (2009). Acta Cryst. D65, 148-155].
- Item2,6-Bis[(S)-4-benzyl-4,5-dihydro-1,3-oxazol-2-yl]pyridine(Chester : International Union of Crystallography, 2011) Möller, K.; Junge, K.; Spannenberg, A.; Beller, M.The commercially available title compound, C25H 23N3O2, has been known since 1993 [Nesper et al. (1993). Helv. Chim. Acta, 76, 2239-2249], but has not been structurally characterized until now. In the free ligand, the N atoms of both oxazoline rings point in opposite directions. The phenyl rings make dihedral angles of 30.56 (5) and 84.57 (3)° with the pyridine ring and 72.85 (3)° with each other.
- ItemN,P,P-Triisopropyl-phosphinic amide(Chester : International Union of Crystallography, 2011) Peulecke, N.; Aluri, B.R.; Müller, B.H.; Spannenberg, A.; Rosenthal, U.The title compound, C9H22NOP, was obtained by slow diffusion of oxygen into a toluene solution of iPr2PNHiPr. In the crystal, an inter-molecular N - H⋯O hydrogen bond occurs.
