Poly[3,3'-diethyl-1,1'-(ethane-1,2-di-yl)diimidazolium [tetra-?-bromido--diargentate(I)]].

ABSTRACT: The asymmetric unit of the title salt, {(C(12)H(20)N(4))[Ag(2)Br(4)]}(n), contains one-half of a substituted imidazolium cation, one Ag(+) and two Br(-) ions. The cation is completed by crystallographic inversion symmetry. The crystal structure is made up from polymeric sheets of {[AgBr(2)](-)}(n) anions extending parallel to (100). The basic building unit of the anion is a slightly distorted AgBr(4) tetra-hedron. A four- and 12-membered ring system is formed by corner sharing of the AgBr(4) tetra-hedra. The imidazolium cations are located between the anionic sheets and partly protrude into the voids defined by the 12-membered rings.

3,3-Dimethyl-1,1-(propane-1,3-di-yl)diimidazol-1-ium tetra-bromido-cadmate(II).

Project description:The title compound, (C(11)H(18)N(4))[CdBr(4)], was prepared by an anion exchange. The dihedral angle between the two planar imidazolium rings in the cation is 74.4?(4)°. The crystal packing is stabilized by weak inter-molecular C-H?Br hydrogen bonds between the cation and the tetrahedral anion, building up a three-dimensionnal network.

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.

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).

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)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)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.
