2-(3-Cyano-4-{7-[1-(2-hy-droxy-eth-yl)-3,3-dimethyl-indolin-2-yl-idene]hepta-1,3,5-trien-yl}-5,5-dimethyl-2,5-dihydro-furan-2-yl-idene)malononitrile.

ABSTRACT: The title compound, C(29)H(28)N(4)O(2), excluding the hydroxyethyl and methyl groups, is slightly twisted from planarity so that the terminating indol-2-yl-idene and furan-2-yl-idene moiety planes subtend a dihedral angle of 6.27?(8)°. A small inwards fold in the polymethine atom chain is consistent with centrosymmetric dimer formation via O-H?N(cyano) hydrogen bonds. In the crystal, the mol-ecules pack in layers approximately parallel to the (10[Formula: see text]) plane via pairs of O-H?N and C-H?N(cyano) inter-actions.

Project description:The title compound, C(20)H(20)N(4)O, is packed into a three-dimensional 'herringbone' matrix using two different types of attractive C-H?N(cyano) inter-actions. The bond-length alternation, caused by delocalization of charge between the donor N atoms and the cyano acceptor groups, is compared with related compounds.

2-(3-Cyano-4-{3-[1-(2-hy-droxy-eth-yl)-3,3-dimethyl-1,3-di-hydro-indol-2-yl-idene]prop-2-en-yl}-5,5-dimethyl-5H-furan-2-yl-idene)malono-nitrile.

Project description:The title compound, C25H24N4O2, adopts a cisoid configuration and has twofold orientational disorder of the 2-hy-droxy-ethyl group. The mol-ecule is twisted from planarity so that the dihedral angle between the terminating indol-2-yl-idene and the furan-2-yl-idene moiety mean planes is 12.75?(7)°. Conformational disorder occurs at the indol-2-yl-idene N atom, which results in two orientations for the hy-droxy-ethyl group [occupancy ratio = 0.896?(2):0.104?(2)], and the hy-droxy O atom of the 2-hy-droxy-ethyl group is located over three sites [occupancy ratio = 0.548?(2):0.348?(2):0.104?(2)]. An intra-molecular C-H?O hydrogen bond involving the lowest occupancy hy-droxy O atom is observed. In the crystal, the mol-ecules pack in parallel dimeric sheets about centres of symmetry, utilizing O-H?N(cyano), C-H?N(cyano) and O-H?O hydrogen bonds, in two sets parallel to (02-1) and (021) planes.

2-[4-(2-{5-tert-Butyl-2-chloro-3-[2-(3-pentyl-1,3-benzothia-zol-2-yl-idene)ethyl-idene]cyclo-hex-1-en-yl}ethen-yl)-3-cyano-5,5-dimethyl-furan-2-yl-idene]malono-nitrile.

Project description:In the title mol-ecule, C36H39ClN4OS, the non-aromatic part of the cyclo-hex-1-enyl ring and the attached tert-butyl group are disordered over two conformations with occupancy ratios of 0.52?(3):0.48?(3) and 0.53?(3):0.47?(3), respectively. The polyene chain single- and double-bond dimensions contrast with a closely related compound [Bouit et al. (2007 ?). Chem. Mater.19, 5325-5335] with an approximate 19° twist between donor and acceptor ends of the mol-ecule, related to the additional intra-molecular C-H?S inter-action. In the title compound, the mol-ecules pack into dimeric units about centres of symmetry utilizing weak C-H?N(cyano) and C-H?O attractive inter-actions, building both chain and ring motifs about the centres [R2(2)(8) and R2(2)(9)]. Adjacent dimeric sets then form a herringbone configuration.

Bis(?-cyclo-hepta-trien-yl)tri-?-hydrido-dimolybdenum(0,I).

Project description:In the title compound, [Mo(2)(?(7)-C(7)H(7))(2)(?-H)(3)], which displays crystallographic mirror symmetry, two (?(7)-C(7)H(7))Mo units are linked along the Mo-Mo axis by three bridging hydride ligands. The Mo-Mo distance is 2.5732?(4)?Å. The perpendicular distances of the Mo atoms from the C(7) planes are 1.5827?(8) and 1.5814?(8)?Å, with individual Mo-C bond lengths in the range 2.261?(2)-2.2789?(14)?Å. Mo-H distances range from 1.77?(3) to 1.85?(4)?Å, with Mo-H-Mo angles of 89?(2) and 92?(1)°.

2-(3-Cyano-4-methyl-5,5-diphenyl-5H-furan-2-yl-idene)malono-nitrile.

Project description:The title compound, C21H13N3O, crystallizes with two independent molecules with similar conformations per asymmetric unit. The dihydrofuran rings are essentially planar with maximum deviations of 0.017?(1) and 0.006?(1)?Å for the O atoms. The dihedral angles between the di-hydro-furan ring and the attached phenyl rings are 79.90?(6) and 82.07?(6)° in one mol-ecule and 79.36?(6) and 72.26?(6)° in the other. In the crystal, the molecules are linked by weak C-H?? and C-H?N inter-actions similar to those in other closely related crystals. The replacement of appended methyl by phenyl groups has not significantly affected the dihydrofuran ring structure or the crystal packing interactions.

2-{3-Cyano-4-[2-(4-diethylamino-2-hy-droxyphenyl)ethenyl]-5,5-dimethyl-2,5-dihydrofuran-2-ylidene}malononitrile acetone 0.25-solvate.

Project description:In the title compound, C(22)H(22)N(4)O(2)·0.25C(3)H(6)O, the disordered acetone mol-ecule lies with partial occupancy about the 2 axis. The mol-ecule of the malononitrile derivative is essentially planar excluding the methyl groups, with the largest deviation from the mean plane through the non-H atoms being 0.1955?(13)?Å. Two rotamers with different orientations of the benzene ring are observed in the ratio of 0.919?(2):0.081?(2), and as a result the OH group is disordered over two sets of sites. In the crystal, the mol-ecules form ribbons along (101) utilizing a strong O-H?N(cyano) hydrogen bond. Inter-leaving of the nearly planar ribbons is provided by the twofold disordered acetone molecule through C-H?O inter-actions.

C-H?? packing inter-actions in 2-[5,5-bis-(4-benzyl-oxyphen-yl)-3-cyano-4-methyl-2,5-dihydro-furan-2-yl-idene]malononitrile.

Project description:The title mol-ecule, C(35)H(25)N(3)O(3), packs utilizing C-H?? attractive inter-actions causing the identical 4-benzyl-oxyphenyl groups to pack with different conformational angles. This difference is consistent with the variable inter-planar dihedral angles found in closely related structures.
