Crystal structure of 1,13,14-tri-aza-dibenz[a,j]anthracene 1,1,2,2-tetra-chloro-ethane monosolvate.

ABSTRACT: The asymmetric unit of the title compound, C19H11N3·C2H2Cl4, consists of one half-mol-ecule of 1,13,14-tri-aza-dibenz[a,j]anthracene (dibenzo[c,h]-1.9,10-anthyridine, dbanth) and one half of 1,1,2,2-tetra-chloro-ethane (TCE), both of which are located on a crystallographic twofold rotation axis. The dihedral angle between the planes of the terminal benzene rings in dbanth is 3.59?(7)° owing to the steric repulsion between the H atoms in the two benzo groups and the H atom in the central pyridine ring of the anthridine skeleton. In the crystal, ?-? inter-actions between pyridine rings [centroid-centroid distances = 3.568?(2) and 3.594?(2)?Å] link the dbanth mol-ecules to form a one-dimensional columnar structure along the c axis. The dbanth and TCE mol-ecules are connected through weak bifurcated C-H?(N,N) hydrogen bonds.

Crystal structure of a 1,1,2,2-tetra-chloro-ethane-solvated hydrazinecarbo-thio-amide compound.

Project description:The title compound, [(1-{4-[2-(2,4-di-hydroxy-phen-yl)diazen-1-yl]phen-yl}ethyl-idene)amino]-thio-urea, 1,1,2,2-tetra-chloro-ethane monosolvate, C15H15N5O2S·C2H2Cl4, was prepared from 4-(4-acetyl-phenyl-diazendi-yl)resorcinol and thio-semicarbazide and recrystallized from mixed solvents of tetra-chloro-ethane and n-hexane. 1H NMR and X-ray diffraction data are in support of the thione tautomeric form. The X-ray analysis shows the mol-ecule crystallizes as a zwitterion, with proton transfer from the nominal phenol to the azide group; the N-N bond length is 1.291?(5)?Å, and an intra-molecular N-H?O hydrogen bond is formed. In the crystal, N-H?O, N-H?N and O-H?S hydrogen bonds connect the mol-ecules into a three-dimensional network. The tetra-chloro-ethane solvent mol-ecules are linked to this network through weak C-H?O linkages.

(2,3,5,10,12,13,15,20-Octa-phenyl-porphinato)copper(II) 1,1,2,2-tetra-chloro-ethane solvate.

Project description:The title complex, [Cu(C(68)H(44)N(4))]·C(2)H(2)Cl(4), exhibits nearly square-planar geometry around the Cu(II) centre and the macrocyclic ring is almost planar. The porphyrin mol-ecule has an approximate non-crystallographic inversion centre (C(i)), and a non-crystallographic twofold rotation axis (C(2)) within the Cu(II)-porphyrin ring plane. Further, it has non-crystallographic twofold rotation axis and mirror plane (C(s)) symmetry perpendicular to the mol-ecular plane. The mol-ecular packing of the complexes and the solvent molecules shows weak inter-molecular C-H⋯π, C-H⋯Cl and C-H⋯N inter-actions, forming a clathrate-like structure.

Crystal structure of bis-(ethyl-enedi-thio)-tetra-thia-fulvalenium μ2-acetato-bis-[tri-bromido-rhenate(III)] 1,1,2-tri-chloro-ethane hemisolvate.

Project description:The asymmetric unit of the title salt, (C10H8S8)[Re2Br6(CH3COO)]·0.5C2H3Cl3, contains one bis-(ethyl-enedi-thio)-tetra-thia-fulvalene (ET) radical cation, one μ2-acetato-bis-[tri-bromido-rhenate(III)] anion and a 1,1,2-tri-chloro-ethane mol-ecule with half-occupancy disordered about a twofold rotation axis. The tetra-thia-fulvalene fragment adopts an almost planar configuration typical of the ET radical cation. The C atoms of both ethyl-enedi-thio fragments in the cation are disordered over two orientations with occupancy factors 0.65:0.35 and 0.77:0.23. In the anion, six Br atoms and a μ2-acetate ligand form a strongly distorted cubic O2Br6 coordination polyhedron around the Re2 dinuclear centre. In the crystal, centrosymmetrically related ET cations and Re2O2Br6 anions are linked into dimers by π-π stacking inter-actions [centroid-to-centroid distance = 3.826 (8) Å] and by pairs of additional Re⋯Br contacts [3.131 (3) Å], respectively. The dimers are further packed into a three-dimensional network by non-directional inter-ionic electrostatic forces and by C-H⋯Br and C-H⋯S hydrogen bonds. The disordered 1,1,2-tri-chloro-ethane mol-ecules occupy solvent-accessible channels along the b axis.

(μ-Ethane-1,1,2,2-tetra-carboxyl-ato)bis-[tetra-aqua-manganese(II)].

Project description:In the centrosymmetric title molecule, [Mn(2)(C(6)H(2)O(8))(H(2)O)(8)], the Mn(II) atom is in an octa-hedral environment coordinated by six O-atom donors from water mol-ecules and ethane-1,1,2,2-tetra-carboxyl-ate ligands. The crystal structure features a three-dimensional hydrogen-bonding network based on a strong and distinctive pattern of O-H⋯O hydrogen-bonding inter-actions.

C(60) 1,1,2,2-tetra-chloro-ethyl-ene tetra-solvate.

Project description:In the title complex, C(60)·4C(2)Cl(4), the C(60) mol-ecule is located on an inversion centre and there are two tetra-chloro-ethyl-ene (TCE) mol-ecules in the asymmetric unit. Both TCE mol-ecules show positional disorder, with occupancy ratios of 0.75:0.25 and 0.56:0.44. Four fullerene C atoms form short contacts [3.208 (17) and 3.223 (17) Å] with the centres of the TCE double bonds, indicating that C(60)-solvent inter-actions are largely π-π in nature.

(4,7,13,16,21,24-Hexaoxa-1,10-di-aza-bicyclo-[8.8.8]hexa-cosa-ne)sodium iodide-1,1,2,2,tetra-fluoro-1,2-diiodo-ethane (2/3).

Project description:The title complex (CX1), [Na(C18H36N2O6)]I·1.5C2F4I2, is a three-component adduct containing a [2.2.2]-cryptand, sodium iodide and 1,1,2,2-tetra-fluoro-1,2-di-iodo-ethane. The di-iodo-ethane works as a bidentate halogen-bonding (XB) donor, the [2.2.2]-cryptand chelates the sodium cation, and the iodide counter-ion acts as a tridentate XB acceptor. A (6,3) network is formed in which iodide anions are the nodes and halocarbons the sides. The network symmetry is C 3i and the I⋯I(-) XB distance is 3.4492 (5) Å. This network is strongly deformed and wrinkled. It forms a layer 9.6686 (18) Å high and the inter-layer distance is 4.4889 (10) Å. The cations, inter-acting with each other via weak O⋯H hydrogen bonds, are confined between two anionic layers and also form a (6,3) net. The structure of CX1 is closely related to that of the KI homologue (CX2). The 1,1,2,2,-tetrafluoro-1,2-diiodoethane molecule is rotationally disordered around the I⋯I axis, resulting in an 1:1 disorder of the C2F4 moiety.

Crystal structure of (2',3,6'-tri-chloro-biphenyl-2-yl)boronic acid tetra-hydro-furan monosolvate.

Project description:The title compound, C12H8BCl3O2·C4H8O, crystallizes as a tetra-hydro-furan monosolvate. The boronic acid group adopts a syn-anti conformation and is significantly twisted along the carbon-boron bond by 69.2?(1)°, due to considerable steric hindrance from the 2',6'-di-chloro-phenyl group that is located ortho to the boronic acid substituent. The phenyl rings of the biphenyl are almost perpendicular to one another, with a dihedral angle of 87.9?(1)° between them. In the crystal, adjacent mol-ecules are linked via O-H?O inter-actions to form centrosymmetric dimers with R 2 (2)(8) motifs, which have recently been shown to be energetically very favourable. The hy-droxy groups are in an anti conformation and are also engaged in hydrogen-bonding inter-actions with the O atom of the tetra-hydro-furan solvent mol-ecule. Cl?Cl halogen-bonding inter-actions [Cl?Cl = 3.464?(1)?Å] link neigbouring dimers into chains running along [010]. Further aggregation occurs due to an additional Cl?Cl halogen bond [Cl?Cl = 3.387?(1)?Å].

1,1,2,2-Tetra-kis(dimethyl-amino)-ethane-1,2-diium bis-(tetra-phenyl-borate) acetone disolvate.

Project description:The title compound, C(10)H(24)N(4) (2+)·2C(24)H(20)B(-)·2C(3)H(6)O, crystallizes with two acetone solvent mol-ecules per asymmetric unit. In the dication, both amidinium units are twisted about the central C-C single bond by 63.8 (3)° and the positive charges are delocalized over both N-C-N planes.

1,1,2,2-Tetra-kis(di-o-tolyl-phosphino)ethane.

Project description:The complete molecule of title compound, C(58)H(58)P(4), is generated by a crystallographic twofold rotation axis that passes through the center of the C(methine)-C(methine) bond of length 1.582?(4)?Å. The C-P bond lengths are 1.8824?(19) and 1.8991?(19)?Å. The P-C-P angle of 109.69?(9)° is essentially equal to the expected value of 109.5° for a tetra-hedral C atom. Although the C(methine)-P-C(aromatic) bond angles range from 102.67?(9) to 107.04?(9)°, the C(aromatic)-P-C(aromatic) bond angles of 96.72?(9) and 97.29?(9)° are significantly smaller. The steric demands of the o-tolyl groups cause deviations from the bond lengths and angles reported for its phenyl analog.

Crystal structure of 1,7,8,9-tetra-chloro-4-(3,5-di-chloro-benz-yl)-10,10-dimeth-oxy-4-aza-tri-cyclo-[5.2.1.0(2,6)]dec-8-ene-3,5-dione.

Project description:In the title compound, C17H11Cl6NO4, the configuration of the cyclo-alkene skeleton is endo,cis. The benzene ring is twisted by 58.94 (8)° from the attached pyrrolidine ring. Two carbonyl groups play a key role in the crystal packing. A short inter-molecular C⋯O distance of 3.017 (3) Å reveals that one carbonyl group is involved in dipole-dipole inter-actions, which link two adjacent enanti-omers into an inversion dimer. Another carbonyl group provides an acceptor for the weak inter-molecular C-H⋯O hydrogen bonds which link these dimers into layers parallel to (011).
