(E)-1,2-Bis{4-[dimeth-yl(vin-yl)silyl]-phenyl}-ethene.

ABSTRACT: 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.

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⋯π contacts as well as van der Waals inter-actions. ...[more]

(S(P),S(P))-(-)-(E)-1,2-Bis(methyl-phenyl-phosphino-yl)ethene.

Project description:The title compound, C(16)H(18)O(2)P(2), possesses two stereogenic P atoms and shows a distorted s-cis conformation of each O=P-C=C moiety. This has been suggested on the basis of the stereochemical result of 1,3-dipolar cyclo-additions with nitro-nes and is now confirmed by the present crystal structure analysis. There are two crystallographically independent molecules in the asymmetric unit.

Poly[[?(2)-1,2-bis-(4-pyrid-yl)ethene](?(3)-1,3-phenyl-enediacetato)-cadmium].

Project description:In the title coordination polymer, [Cd(C(10)H(8)O(4))(C(12)H(10)N(2))](n), two centrosymmetrically related Cd(II) atoms are bridged by two 1,3-phenyl-enediacetate ligands forming a chain along the [100] direction. The distorted penta-gonal-bipyramidal coordination about each metal atom is completed by the N atoms of bridging 1,2-bis-(4-pyrid-yl)ethene ligands, which link these one-dimensional chains into a two-dimensional net extending along the (101) plane.

trans-1,2-Bis(3,5-dimethoxy-phen-yl)ethene.

Project description:The title compound, C(18)H(20)O(4), was prepared in high yield from 3,5-dimethoxy-styrene via a Ru-catalysed homo-olefin metathesis. Exclusive formation of the E-configurated isomer was observed. Inter-estingly, one symmetric unit contains two mol-ecules adopting an s-syn-anti and and an all-s-anti conformation.

Poly[[bis-[?2-1,2-bis-(pyridin-4-yl)ethene-?(2) N:N']bis-(thio-cyanato-?N)cobalt(II)] 1,2-bis-(pyridin-4-yl)ethene monosolvate dihydrate].

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.

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

Project description: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.

Project description:In the title mol-ecule, C(26)H(22)P(2)Se(2), both P atoms have distorted tetra-hedral environments, resulting in effective cone angles of 177 and 174°. Inversion twinning was detected and refined to a ratio of 0.35:0.65. Weak inter-molecular C-H?Se inter-actions are observed.

(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.

2,3-Bis{[2,3-dimethyl-6-(phenyl-vin-yl)phen-yl]imino}-butane.

Project description:In the title compound, C36H36N2, a product of the condensation reaction of 2,3-dimethyl-6-phenyl-vinyl-benzenamine and 2,3-butane-dione, the complete mol-ecule is generated by the application of an inversion centre. The central C-C bond in the 1,4-di-aza-butadiene fragment is trans-configured and situated about the inversion center. The dihedral angle between the ring attached to N and the 1,4-di-aza-butadiene plane is 78.24 (36)°, while the 1,4-di-aza-butadiene plane makes an angle of 30.71 (26)° with the phenyl ring.

1,2-Bis(phenyl-phosphor-yl)ethane.

Project description:The geometric parameters of the mol-ecule of the title compound, C(14)H(16)O(2)P(2), are in the usual ranges. It is a meso compound with the two chiral P atoms having opposite configurations. The P-CH(2)-CH(2)-P chain adopts a trans conformation [torsion angle -178.59 (17)°]. The P=O bonds are almost coplanar with the adjacent phenyl ring [torsion angles = 3.8 (3) and 0.3 (3)°]. Whereas one of them is synclinal [torsion angle = -59.0 (2)°] to the central C-C bond, the other is anti-clinal [torsion angle = 56.6 (2)°] to the central C-C bond. The dihedral angle between the two phenyl rings is 5.2 (3)°. The mol-ecules are linked by weak C-H⋯O hydrogen bonds. They crystallize in rows running along the c axis.
