4,4'-(Ethane-1,2-diyl)dipyridinium bis-(2-hy-droxy-benzoate).

ABSTRACT: In the crystal structure of the title compound, C(12)H(14)N(2) (2+)·2C(7)H(5)O(3) (-), the cations and anions are linked via N-H?O hydrogen bonds and weak inter-molecular C-H?O inter-actions also occur. ?-? stacking is observed between the nearly parallel benzene and pyridine rings [dihedral angle = 6.03?(8)°], the centroid-centroid separation being 3.7546?(16)?Å. The 4,4'-(ethane-1,2-diyl)dipyridinium cation is centrosymmetric and the mid-point of the ethyl-ene C-C bond is located on an inversion center. An intra-molecular O-H?O hydrogen bond occurs in the anion.

2,2'-[(1E,2E)-1,2-Bis(hy-droxy-imino)-ethane-1,2-di-yl]dipyridinium hexa-chloridorhenate(IV).

Project description:The title salt, (C(12)H(12)N(4)O(2))[ReCl(6)], consists of 2,2'-[(1E,2E)-1,2-bis-(hy-droxy-imino)-ethane-1,2-di-yl]dipyridinium cations and [ReCl(6)](2-) anions which are both located on inversion centres. Each cation consists of a glyoxime moiety attached to two protonated pyridine rings in ortho positions. In the crystal, E,E isomers of the cation are observed which differ in the spatial arrangement of the pyridine rings. These rings are positionally disordered over two positions with site-occupancy factors of 0.786 (7) and 0.214 (7). The geometry of the cation is compared with that of a recently reported dipyridyl-glyoxime with the same configuration. The cations and anions are involved in a network of inter-molecular O-H⋯Cl, N-H⋯Cl and C-H⋯Cl hydrogen bonds.

Project description:The title compound, (C12H16N3O)[PtCl4]Cl, consists of a 4,4'-(1-aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium trication, a square-planar tetra-chloridoplatinate(II) dianion and a chloride ion. In the cation, the pyridinium rings attached to the central 1-aza-niumyl-2-hy-droxy-ethane fragment have an anti conformation, as indicated by the central C-C-C-C torsion angle of -166.5?(6)°, and they are inclined to one another by 63.5?(4)°. In the crystal, the cations and anions are linked through N-H?Cl and O-H?Cl hydrogen bonds. There are also ?-? contacts [centroid-centroid distances = 3.671?(4) and 3.851?(4)?Å] and a number of C-H?Cl inter-actions present, consolidating the formation of a three-dimensional supra-molecular structure.

Bis[(1RS,2RS)-4,4'-(1-aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium] tris-[tetra-chloridopalladate(II)].

Project description:The asymmetric unit of the title compound, (C12H16N3O)2[PdCl4]3, consists of a 4,4'-(1-aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium dication and one and a half tetra-chloridopalladate(II) anions; the latter has inversion symmetry.

1,1'-(Ethane-1,2-di-yl)dipyridinium bis-(iodate).

Project description:The title salt, C(12)H(14)N(2) (2+)·2IO(3) (-), exhibits two crystallographically independent iodate anions, the I atoms of which are each in a trigonal-pyramidal environment. In the dication, the two pyridine rings adopt an anti conformation with respect to each other; the angle between these two rings is 3.84 (19)°. In the crystal structure, C-H⋯O hydrogen bonds between the cations and anions lead to the formation of layers arranged parallel to the ab plane. I⋯O halogen bonds [R(2) (2)(4) graph-set motif] range between 2.873 (2) and 3.036 (3) Å and connect neighbouring IO(3) (-) anions with each other along [100], so as to create a three-dimensional network.

4,4'-[Propane-1,2-diyl-bis(nitrilo-methyl-idyne)]-dibenzo-nitrile-4,4'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]dibenzonitrile [0.796 (2)/0.204 (2)].

Project description:The title cocrystal, 0.796C(19)H(16)N(4)·0.204C(18)H(14)N(4), is a disordered mixture of two potentially bidentate Schiff base ligands. The difference in the two components of the cocrystal is the replacement of the methyl group in the linkage between the imine N atoms in the major component of the Schiff base ligand by an H atom. The imino (C=N) functional groups are coplanar with the benzene rings (only the major component) and extend in opposite directions (both components). Inter-molecular π-π inter-actions with a centroid-to-centroid distance of 3.7371 (8) Å are observed in the crystal packing.

(±)-Cyclo-hexane-1,2-diyl bis-(4-nitro-benzoate).

Project description:The crystal structure of the title compound, C(20)H(18)N(2)O(8), has been investigated to establish the relative stereochemistry between the ester groups. The cyclo-hexane ring adopts a chair conformation, in which the two ester groups occupy the adjacent equatorial positions in a trans relationship with each other. The mol-ecules assemble in the crystal as chains along the c axis via C-H⋯π inter-actions between the cyclo-hexane ring and a pair of nitro-phenyl rings of the neighbouring mol-ecule. Also observed are π-π stacking inter-actions between the nitro-phenyl rings of neighbouring chains, with a perpendicular distance between these rings of 3.409 Å and a slippage of 0.969 Å.

Project description:In the title compound, [Mn(C(16)H(12)Br(2)N(2)O(2))(N(3))], the Mn(III) ion is chelated by a tetra-dentate Schiff base ligand and coordinated by the N atom of an azide ligand in a distorted square-pyramidal arrangement. It forms phenolate-bridged out-of-plane dimers with Mn⋯O(phenolate) distances of 2.667 (2) Å between pairs of inversion-related mol-ecules. In the crystal, there are offset inter-complex face-to-face π-π inter-actions [centroid-centroid distances = 3.598 (2) Å] involving one of the benzene rings of the ligands.
