In the dianion, the Cr(VI) ions are in a slightly distorted tetra-hedral coordination environment and the bond angles at the independent Cr(VI) ions are in the ranges 105.93?(10)-110.60?(11) and 107.35?(11)-111.07?(12)°. The Cr-O-Cr angle is 127.96?(12)°. The crystal used was an inversion twin with refined components of 0.510?(19) and 0.490?(19).

In the dianion, the Cr(VI) ions are in a slightly distorted tetra-hedral coordination environment and the bond angles at the independent Cr(VI) ions are in the ranges 105.93 (10)-110.60 (11) and 107.35 (11)-111.07 (12)°.

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.

1,1'-(Ethane-1,2-di-yl)dipyridinium bis-(1,2-di-cyano-ethene-1,2-di-thiol-ato-κ(2) S,S')cuprate(II).

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. The dihedral angles between the 1,2-di-cyano-ethene-1,2-di-thiol-ato ligands and between the two pyridine rings in the cation are 37.49 (3) and 29.18 (10)°, respectively. Weak C-H⋯N and C-H⋯S hydrogen bonds link the cations and anions into 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.

6,6'-Di-nitro-1,1'-(ethane-1,2-di-yl)di(1H-indazole).

Project description:The mol-ecule of the title compound, C16H12N6O4, is built up from two fused five- and six-membered rings linked by an ethyl-ene group. The dihedral angle between the planes through the indazole ring systems is 39.74 (5)°. The nitro groups are tilted by 7.2 (2) and 8.5 (2)° with respect to planes of the fused-ring systems. In the crystal, mol-ecules are linked by C-H⋯N and C-H⋯O hydrogen bonds into chains running parallel to the c 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.

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 organic cation has an inversion center at the mid-point of the ethane C-C bond. In the anion, the Pb(II) atom is coordinated by six I atoms in a distorted octa-hedral geometry. 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.

Project description:The organic cation in the title compound, C(14)H(18)N(2) (2+)·2Br(-)·2H(2)O, is situated on an inversion centre. The cations, anions and water mol-ecules are linked via O-H⋯Br, C-H⋯Br and C-H⋯O hydrogen bonds, and π-π stacking inter-actions between adjacent pyridine rings, with a centroid-centroid separation of 3.8518 (17) Å.

3,3'-Dibenzoyl-1,1'-dibenzyl-1,1'-(ethane-1,2-di-yl)-dithio-urea.

Project description:In the title compound, C(32)H(30)N(4)O(2)S(2), the carbonyl and thio-carbonyl groups are found in a rare synclinal conformation, with an S-C?C-O pseudo-torsion angle of 62.6?(2)°. The mol-ecule has C(i) = S(2) point-group symmetry with a crystallographic center of inversion located in the middle of the ethyl-ene bridge. One of the symmetry-independent phenyl rings is disordered over two orientations, with a site-occupation ratio of 70:30. The distances between the centroids of the nearest phenyl rings are equal to one of the lattice constants [a = 4.7767?(2)?Å], so stacking inter-actions are extremely weak. Mol-ecules are joined by bifurcated hydrogen bonds (N-H?O and N-H?S), forming a ladder-like arrangement along [100]. van der Waals forces combine these ladders into a three-dimensional structure. The dependency between the S?O distance and the improper S=C?C=O torsion angle based on 739 structures containing the CC(=O)NC(=S)N moiety is discussed.
