    Tetra­carbonyl-2κ4C-[μ-5-methyl-1,1,3-triphenyl-2-(propan-2-yl)-2,4-di­aza-1,3-diphosphahexan-4-ido-1κN4:2κP1,P3](N,N,N′,N′-tetra­methyl­ethane-1,2-di­amine-1κ2N,N′)lithiummolybdenum
    (Chester : IUCr, 2018) Höhne, Martha; Spannenberg, Anke; Müller, Bernd H.; Peulecke, Normen; Rosenthal, Uwe
    The title complex, [LiMo(C6H16N2)(C24H29N2P2)(CO)4], contains a distorted octa­hedrally coordinated molybdenum centre bearing a li­thia­ted P,P′-cis-chelating PNPN ligand, which results in a nearly planar four-membered metallacycle. The Li atom is coordinated by one equivalent tetra­methyl­ethylenedi­amine. In the crystal, mol­ecules are linked via weak C—H...O inter­actions, forming a chain along the b-axis direction.

    Tetra­carbon­yl[N-(di­phenyl­phosphanyl-κP)-N,N′-diisoprop­yl-P-phenyl­phospho­rus di­amide-κP]molybdenum(0) with an unknown solvent
    (Chester : IUCr, 2018) Höhne, Martha; Gongoll, Marc; Spannenberg, Anke; Müller, Bernd H.; Peulecke, Normen; Rosenthal, Uwe
    The title complex, [Mo(C24H30N2P2)(CO)4], contains a molybdenum centre bearing a P,P′-cis-chelating Ph2PN(iPr)P(Ph)NH(iPr) and four carbonyl ligands in a distorted octa­hedral coordination geometry. This results in a nearly planar four-membered metallacycle. In the crystal, mol­ecules are linked by N—H...O and C—H...O hydrogen bonds to form layers parallel to the ac plane. For the final refinement, the contributions of disordered solvent mol­ecules were removed from the diffraction data with SQUEEZE in PLATON [Spek (2015). Acta Cryst. C71, 9–18]. The given chemical formula and other crystal data do not take into account the unknown solvent mol­ecule(s).

    3,3′-Dimethyl-1,1′-methyl­enediimidazolium tetra­bromido­cobaltate(II)
    (Chester : IUCr, 2018) Peppel, Tim; Spannenberg, Anke
    The title compound, (C9H14N4)[CoBr4], was obtained as single crystals directly in very low yield as a side product in the reaction of 1,1′-bis­(1-methyl­imidazolium)acetate bromide and CoBr2. The title compound consists of an imidazolium-based dication and a tetra­bromido­cobaltate(II) complex anion, which are connected via C—H...Br inter­actions in the crystal. The dihedral angle between the imidazolium rings in the cation is 72.89 (16)°. The CoII ion in the anion is coordinated tetra­hedrally by four bromide ligands [Co—Br = 2.4025 (5)–2.4091 (5) Å and Br—Co—Br = 106.224 (17)–113.893 (17)°]. The compound exhibits a high melting point (>300°C) and is a light-blue solid under ambient conditions.

    Tetra­carbon­yl[4,4-dimethyl-2-(pyridin-2-yl)-2-oxazoline-κ2N,N′]molybdenum(0)
    (Chester : IUCr, 2019) Steinlechner, Christoph; Spannenberg, Anke; Junge, Henrik; Beller, Matthias
    In the title compound, [Mo(C10H12N2O)(CO)4], the molybdenum(0) center is surrounded by a bidentate di­imine [4,4-dimethyl-2-(pyridin-2-yl)-2-oxazoline] and four carbonyl ligands in a distorted octa­hedral coordination geometry. The di­imine ligand coordinates via the two nitro­gen atoms.

    1-Di­phenyl­phosphanyl-2-(di­phenyl­phosphor­yl)hydrazine
    (Chester : IUCr, 2018) Höhne, Martha; Aluri, Bhaskar; Spannenberg, Anke; Müller, Bernd H.; Peulecke, Normen; Rosenthal, Uwe
    The title compound, C24H22N2OP2, is an asymmetrically substituted hydrazine derivative bearing a phosphoryl and a phosphanyl substituent. The PNNP backbone has a torsion angle of −131.01 (8)°. In the crystal, mol­ecules form centrosymmetric dimers by inter­molecular N—H...O hydrogen bonds, which are further linked into a three-dimensional network by weak C—H...O and C—H...π inter­actions.

    Crystal structure of tricarbonyl(N-diphenylphosphanyl-N,N'-diisopropyl-P-phenylphosphonous diamide-κ2 P,P')cobalt(I) tetracarbonylcobaltate(-I) toluene 0.25-solvate
    (Chester : International Union of Crystallography, 2014) Dura, L.; Spannenberg, A.; Beweries, T.
    The asymmetric unit of the title compound, [Co(C24H30N2P2)(CO)3][Co(CO)4]·0.25C7H8, consists of two crystallographically independent cations with similar conformations, two anions, and one-half of a toluene molecule disordered about an inversion centre. In the cations, a Co/P/N/P four-membered slightly bent metallacycle is the key structural element. The pendant NH group is not coordinated to the CoI atom, which displays a distorted trigonal-bipyramidal coordination geometry. Weak interionic hydrogen bonds are observed between the NH groups and a carbonyl group of the tetrahedral [Co(CO)4]- anions.
