(Z)-1,2-Dichloro-1,2-bis-(3-chloro-quinoxalin-2-yl)ethene.

ABSTRACT: The title compound, C(18)H(8)Cl(4)N(4), exists in a cis configuration with respect to the bridging C=C bond. The two essentially planar quinoxaline ring systems [maximum deviations = 0.012?(1) and 0.022?(1)?Å] are inclined at an angle of 59.84?(3). In the crystal, adjacent mol-ecules are linked into chains propagating along [001] via inter-molecular C-H?N hydrogen bonds. Weak inter-molecular ?-? [centroid-centroid distance = 3.6029?(7)°] and C-H?? inter-actions are also observed.

The title compound, C(18)H(8)Cl(4)N(4), exists in a cis configuration with respect to the bridging C=C bond. The two essentially planar quinoxaline ring systems [maximum deviations = 0.012 (1) and 0.022 (1) Å] are inclined at an angle of 59.84 (3). In the crystal, adjacent mol-ecules are linked into chains propagating along [001] via inter-molecular C-H⋯N hydrogen bonds. Weak inter-molecular π-π [centroid-centroid distance = 3.6029 (7)°] and C-H⋯π inter-actions are also observed. ...[more]

Project description:The asymmetric unit of the title compound, {[Co(NCS)2(C12H10N2)2]·C12H10N2·2H2O} n , consists of two independent Co(II) cations, four distinct thio-cyanate anions, six 1,2-bis-(pyridin-4-yl)ethene (4-bpe) mol-ecules and four lattice water mol-ecules. The Co(II) cations are each coordinated by two N-bonded thio-cyanate anions and four 4-bpe ligands within a slightly distorted CoN6 octa-hedron. The two independent Co(II) cations are linked by the 4-bpe ligands into two distinct layers, parallel to the ac and bc planes, that inter-penetrate. From this arrangement, channels are formed in which non-coordinated 4-bpe and lattice water mol-ecules are hydrogen-bonded into chains that elongate in the c-axis direction.

(E)-1,2-Bis(1-allyl-benzimidazol-2-yl)ethene.

Project description:In the title compound, C(22)H(20)N(4), the two benzimidazole ring systems are nearly coplanar [dihedral angle = 4.70 (5)°]. Two terminal C atoms of one allyl group are disordered over two sites of equal occupancy. The crystal structure is stabilized by π-π stacking inter-actions, the centroid-centroid distance between nearly parallel [dihedral angle = 19.82 (4)°] benzene and imidazole rings being 3.7885 (15) Å.

Project description:The mol-ecule of the title compound, C(32)H(34)Si(2), is situated about a centre of symmetry. The whole diphenyl-ethene fragment is planar and the C(ar)-Si-C(3) group is rotated by ca 30° with respect to the plane of the benzene ring. The crystal structure is stabilized by some C-H?? contacts as well as van der Waals inter-actions.

A triclinic polymorph of poly[[bis-[μ-1,2-bis-(pyridin-4-yl)ethene-κ(2)N:N']bis-(thio-cyanato-κN)cobalt(II)] 1,2-bis-(pyridin-4-yl)ethene monosolvate].

Project description:In the crystal structure of the title compound, [Co(NCS)(2)(C(12)H(10)N(2))(2)]·C(12)H(10)N(2), the Co(II) cations are octa-hedrally coordinated by two terminally N-bonded thio-cyanate anions and four 1,2-bis-(pyridin-4-yl)ethene (bpe) ligands. The asymmetric unit consists of three crystallographically independent Co(II) cations, six thio-cyanate anions and six coordinating bpe ligands in general positions. Additionally, three non-coordin-ating bpe ligands are present in the asymmetric unit with two of them located on a center of inversion. The Co(II) cations are connected by the bpe ligands into layers parallel to the bc plane. The crystal investigated was non-merohedrically twinned, with a fractional contribution of 0.261 (2) for the minor domain.

Bis[1-(3-cyano-benz-yl)pyridinium] bis-(1,2-dicyano-ethene-1,2-dithiol-ato)nickelate(II).

Project description:In the ionic title complex, (C(13)H(11)N(2))(2)[Ni(C(4)N(2)S(2))(2)], the Ni(II) ion is located on an inversion centre so the asymmetric unit contains one-half [Ni(mnt)(2)](2-) dianion (mnt(2-) is maleonitrile-dithiolate) and one 1-(3-cyano-benz-yl)pyridinium cation ([CNBzPy](+)). The Ni(II) ion in the [Ni(mnt)(2)](2-) anion is coordinated by four S atoms of two mnt(2-) ligands, and exhibits square-planar coordination geometry. In the [CNBzPy](+) cation, the benzene and pyridine rings are twisted with respect to the C/C/N plane incorporating the methyl-ene C atom that links them. The crystal structure is stabilized by Coulombic inter-actions.

Tetraphenyl-arsonium cis-bis-[1,2-bis-(tri-fluoro-meth-yl)ethene-1,2-dithiol-ato]platinate(II).

Project description:In the title compound, (C(24)H(20)As)[Pt(C(4)F(6)S(2))(2)], the cation lies on a twofold rotation axis while the anion has crystallographic inversion symmetry.

Bis[1-(4-cyano-benz-yl)pyrazinium] bis-(1,2-dicyano-ethene-1,2-dithiol-ato)nickelate(II).

Project description:The asymmetric unit of the title complex, (C(12)H(10)N(3))(2)[Ni(C(4)N(2)S(2))(2)], consists of one 1-(4-cyano-benz-yl)pyrazinium cation and one half of an [Ni(mnt)(2)](2-) dianion (mnt(2-) is 1,2-dicyano-ethene-1,2-dithiol-ate). The Ni(2+) ion is located on an inversion center and is coordinated by four S atoms from two mnt(2-) ligands, exhibiting a square-planar coordination geometry.

Poly[[bis-[?-1,2-bis-(4-pyrid-yl)ethene]bis-(trichloro-acetato)-cadmium(II)] monohydrate].

Project description:In the crystal structure of the title compound, {[Cd(C(2)Cl(3)O(2))(2)(C(12)H(10)N(2))(2)]·H(2)O}(n), the Cd(II) ion lies on a twofold rotation axis and 1,2-bis-(4-pyrid-yl)ethene ligands bridge symmetry-related Cd(II) ions, forming a two-dimensional structure. Two trichloro-acetate ligands complete the coordination around the Cd(II )ion, forming a distorted octa-hedral environment. In the crystal, solvent water mol-ecules, which also lie on twofold rotation axes, form inter-molecular O-H?O hydrogen bonds, which connect the two-dimensional structure into a three-dimensional network. The crystal studied was an inversion twin, the refined ratio of twin components being 0.75?(4):0.25?(4).
