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

ABSTRACT: 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.

1,1'-(Ethane-1,2-di-yl)bis-(1,4,7-triazonane).

Project description:In the centrosymmetric title compound (dtne), C(14)H(32)N(6), two 1,4,7-triaza-cyclo-nonane (tacn, or 1,4,7-triazonane) moieties are linked together each at an amino position by a single ethyl-ene spacer. The mol-ecular packing is supported by pairs of inter-molecular N-H?N hydrogen bonds, which form R(2) (2)(22) ring motifs and link the mol-ecules into infinite chains running parallel to the a axis.

1,1'-(Ethane-1,2-di-yl)bis-(indoline-2,3-dione).

Project description:The mol-ecule of the title compound, C(18)H(12)N(2)O(4), is situated on a crystallographic centre of symmetry. The mol-ecule has a zigzag structure, with two parallel symmetry-related indoline-2,3-dione fragments linked by an ethyl-ene group at each N atom. In the crystal, the mol-ecules stack in columns along the b axis. There are two such columns in the structure. The mol-ecules within each column are parallel; however, the mol-ecules in the two columns differ in the respective orientation of the indoline-2,3-dione fragments. In one column, they are approximately parallel to (112), while in the other they are approximately parallel to (12). The inter-planar angle between the indoline-2,3-dione fragments in the two columns is 80.83?(3)°. The mol-ecules within each column are related by mutual displacement of their centres of symmetry, that is (0, ±1/2, ±1/2). The packing between the mol-ecules is provided by weak inter-actions only, viz. C-H?O hydrogen bonds and ?-? [centroid-centroid distance = 3.8745?(8)?Å] and C=O?? inter-actions.

Project description:In the title ion-pair complex, (C12H14N2)[Cu(C4N2S2)2], the complex anion exhibits a highly twisted coordination environment around the tetra-coordinated Cu(II) atom.

catena-Poly[1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium [lead(II)-tri-μ-iodido-lead(II)-tri-μ-iodido]].

Project description:The title compound, {(C(14)H(18)N(2))[Pb(2)I(6)]}(n), consists of discrete 1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium cations and one-dimensional [Pb(2)I(6)](n) anions.

The I atoms bridge the Pb(II) atoms into a polymeric chain running along [001]. These inorganic chains are separated by the isolated organic cations.

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.
