Bis(2,4-dioxo-pentan-3-ido-κ² O,O')dioxidomolyb-denum(VI): a redetermination.

ABSTRACT: The title compound, [Mo(C₅H₇O₂)₂O₂] or cis-[MoO₂(acac)₂] (acac is acetyl-acetonate), contains a molybdenum(VI) atom coordinated by two acetyl-acetonate ligands and two doubly bonded oxido ligands in a distorted octa-hedral shape. The mol-ecule is chiral and the asymmetric unit contains two independent mol-ecules (one Δ, one Λ). Extensive C-H⋯O contacts are present throughout the structure. Data were collected at 100 K, providing higher precision of unit-cell parameters and atomic positions than previous determinations [Kamenar et al. (1973 ▸). Cryst. Struct. Commun. 2, 41-44.; Krasochka et al. (1975). Zh. Strukt. Khim. 16, 696-698].

Bis(2,4-dioxo-5,5-diphenyl-imidazol-idin-ido-κN)bis-(propane-1,3-diamine-κN,N')cobalt(II).

Project description:The complex mol-ecule of the title compound, [Co(C(15)H(11)N(2)O(2))(2)(C(3)H(10)N(2))(2)], has crystallographically imposed inversion symmetry. The Co(II) atom displays a distorted octa-hedral coordination geometry. In the phenytoin anion, the two phenyl rings form dihedral angles of 62.26 (8) and 57.47 (9)° with the central imidazole ring. Intra-molecular N-H⋯O and C-H⋯O hydrogen bonds occur. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds forming a three-dimensional network.

Redetermination of 2,4'-methyl-ene-diphenol.

Project description:In the previous determination [Finn & Musti (1950 ▶). J. Soc. Chem. Ind. (London), 69, S849] of the title compound, C(13)H(12)O(2), the three-dimensional coordinates and displacement parameters were not reported. This redetermination at room temperature reveals that the dihedral angle between the benzene rings is 79.73 (6)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds between adjacent mol-ecules result in two-dimensional wave-like supra-molecular motifs parallel to the ab plane.

Redetermination of di-μ-hydroxido-bis-[diaqua-chlorido-dioxido-uranium(VI)] from single-crystal synchrotron data.

Project description:The title compound, [(UO(2))(2)Cl(2)(OH)(2)(H(2)O)(4)], was obtained unintentionally as the product of an attempted reaction between uranium(VI) oxide dihydrate, UO(3)·2H(2)O, and hydrogen bis-(trifluoro-methyl-sulfon-yl)imide (HTf(2)N), in an experiment to obtain crystals of uranyl bis-(trifluoro-methyl-sulfon-yl)imide, UO(2)(Tf(2)N)(2)·xH(2)O. The structure consists of neutral dimers of uranyl (UO(2) (2+)) units, double bridged by OH(-) anions. Each uranyl unit is surrounded by one Cl and four O atoms, which form an irregular penta-gon, in a plane perpendicular to the linear uranyl groups. The coordination geometry around each U atom can be considered to be distorted penta-gonal-bipyramidal. In the crystal structure the uranyl dimers are connected to each other by hydrogen-bonding inter-actions [O⋯Cl = 3.23 (1) Å].

Redetermination of hexa-sodium hepta-molybdate(VI) 14-hydrate.

Project description:The structure of the title compound, Na(6)(Mo(7)O(24))·14H(2)O, has been redetermined [Sjöbom & Hedman (1973). Acta Chem. Scand.27, 3673-3674] and the hydrogen atoms have been located. The Na(+) cations adopt distorted octa-hedral geometries and the structure of the [Mo(7)O(24)](6-) anion is consistent with those of other hepta-molbydates. In the crystal, numerous O-H⋯O hydrogen bonds help to establish the packing.

(Acetyl-acetonato)dibromido[2,2-diphenyl-hydrazin-1-ido(1-)][2,2-diphenyl-hydrazin-1-ido(2-)]molybdenum(VI).

Project description:In the title compound, [MoBr(2)(C(12)H(11)N(2))(C(12)H(10)N(2))(C(5)H(7)O(2))], the Mo(VI) atom is six-coordinated in a distorted octa-hedral geometry by two N atoms from the diphenyl-hydrazide(1-) and diphenyl-hydrazide(2-) ligands, two O atoms from a bidentate acetyl-acetonate ligand and two Br(-) ions. The mol-ecules form an inversion dimer via a pair of weak C-H⋯O hydrogen bonds and a π-π stacking inter-action with a centroid-centroid distance of 3.7401 (12) Å. Weak intra-molecular C-H⋯Br inter-actions and an intra-molecular π-π stacking inter-action with a centroid-centroid distance of 3.8118 (15) Å are also observed.

A redetermination of bis-(5,5'-diethyl-barbiturato)bis-(imidazole)cobalt(II).

Project description:The title complex, [Co(C(8)H(12)N(2)O(3))(2)(C(3)H(4)N(2))(2)], whose structure was first determined by Wang & Craven [(1971). J. Chem. Soc. D, pp. 290-291], has been redetermined with improved precision. A crystallographic twofold rotation axis passes through the Co atom, which is tetrahedrally coordinated by two N atoms from two barbital ligands and two N atoms from two imidazole ligands. The mol-ecules are self-assembled via inter-molecular N-H⋯O hydrogen-bonding inter-actions into a supra-molecular network.

Bis(ethanol-κO)bis(1-ferrocenyl-4,4,4-trifluorobutane-1,3-dionato-κ2O,O′)nickel(II)

Project description:In this novel trimetallic complex, the central NiII ion is six-coordinate, forming an octahedral [NiO6] core. In the title compound, [NiFe2(C5H5)(C9H5F3O2)2(C2H6O)2], the central NiII ion is observed in an octahedral coordination environment. The chelating β-diketonate ligands are substituted by ferrocene, a lipophilic organometallic moiety. The ferrocene groups have the normal geometry, with eclipsed cyclopentadiene rings. Coordinated ethanol molecules are engaged in intermolecular hydrogen bonds, and the crystal is further stabilized by weak C—H⋯F and C—H⋯π contacts.

Crystal structure and Hirshfeld surface analysis of aqua-bis-(nicotinamide-κN1)bis-(2,4,6-tri-methyl-benzoato-κ2O,O')cadmium(II).

Project description:The asymmetric unit of the title complex, [Cd(C10H11O2)2(C6H6N2O)2(H2O)], contains one half of the complex mol-ecule, with the CdII cation and the coordinated water O atom residing on a twofold rotation axis. The CdII cation is coordinated in a bidentate manner to the carboxyl-ate O atoms of the two symmetry-related 2,4,6-tri-methyl-benzoate (TMB) anions and to the water O atom at distances of 2.297 (2), 2.527 (2) and 2.306 (3) Å to form a distorted penta-gonal arrangement, while the distorted penta-gonal-bipyramidal coordin-ation sphere is completed by the two pyridine N atoms of the two symmetry-related monodentate nicotinamide (NA) ligands at distances of 2.371 (3) Å in the axial positions. In the crystal, mol-ecules are linked via inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds with R22(12), R33(8), R33(14), R33(16), R33(20), R33(22), R44(22), R55(16), R66(16) and R66(18) ring motifs, forming a three-dimensional architecture. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are H⋯H (56.9%), H⋯C/C⋯H (21.3%) and H⋯O/O⋯H (19.0%) inter-actions.

Redetermination of μ-oxido-bis-[bis-(N,N-diethyl-hydroxyl-aminato)-oxido-vanadium(V)].

Project description:In comparison with the previous determination [Saussine, Mimoun, Mitschler & Fisher (1980 ▶). Nouv. J. Chim.4, 235-237] of the title compound, [V(2)(C(4)H(10)NO)(4)O(3)], the current study reports an improved precision of the derived geometric parameters, along with the deposition of all coordinates and displacement parameters. The two V(V) atoms are each surrounded by two deprotonated N,O-bidentate diethyl-hydroxy-laminate groups, and a terminal and a bridging oxide ligand, in a distorted octa-hedral coordination geometry. The crystal packing is accomplished by van der Waals inter-actions.

Diaqua-bis(2,4-dichloro-6-formyl-phenolato)zinc(II)-bis-(μ-2,4-dichloro-6-formyl-phenolato)bis-[aqua-(2,4-dichloro-6-formyl-phenolato)zinc(II)] (2/1).

Project description:The crystal of the title compound, [Zn(C(7)H(3)Cl(2)O(2))(2)(H(2)O)(2)](2)·[Zn(2)(C(7)H(3)Cl(2)O(2))(4)(H(2)O)(2)], consists of monomeric and dimeric Zn(II) complexes. Both complexes afford a six-coordinated coordination environment about the Zn atoms with cis-configuration ligands. The deprotonated hydr-oxy groups of the 3,5-dichloro-salicylaldehyde ligands bridge two metal cations, forming a centrosymmetric dimeric complex. Inter-molecular O-H⋯O hydrogen bonding occurs between the coordinated water mol-ecules and deprotonated hydr-oxy groups in the crystal structure.
