The vinyl-aldehyde group adopts an extended conformation wih a C-C-C-C torsion angle of 179.7?(4)°.

The vinyl-aldehyde group adopts an extended conformation wih a C-C-C-C torsion angle of 179.7 (4)°. In the crystal, mol-ecules are linked by classical O-H⋯O and weak C-H⋯O hydrogen bonds into a three-dimensional supra-molecular network. ...[more]

Crystal structure of 5-[2-(2,4,6-tri-bromo-phen-yl)diazen-yl]tropolone.

Project description:The title compound {systematic name: 2-hy-droxy-5-[2-(2,4,6-tri-bromo-phen-yl)diazen-1-yl]cyclo-hepta-2,4,6-trien-1-one}, C13H7Br3N2O2, is essentially planar, with an r.m.s. deviation of 0.054?Å. The mol-ecular structure is fixed in the azo tautomer by intra-molecular C-H?N inter-actions, with O-H?O hydrogen bonds creating linked dimers. Charge-transfer inter-actions are observed, with the segregated stacks linked by Br?Br inter-actions.

Crystal structure of 2-(3-bromo-phen-yl)-1,3-di-thiane.

Project description:In the title compound, C10H11BrS2, the 1,3-di-thiane ring has a chair conformation with the 1,4-disposed C atoms being above and below the remaining four atoms. The bromo-benzene ring occupies an equatorial position and forms a dihedral angle of 86.38 (12)° with the least-squares plane through the 1,3-di-thiane ring. Thus, to a first approximation the mol-ecule has mirror symmetry with the mirror containing the bromo-benzene ring and the 1,4-disposed C atoms of the 1,3-di-thiane ring. In the crystal, mol-ecules associate via weak methyl-ene-bromo-benzene C-H⋯π and π-π [Cg⋯Cg = 3.7770 (14) Å for centrosymmetrically related bromo-benzene rings] inter-actions, forming supra-molecular layers parallel to [10-1]; these stack with no specific inter-molecular inter-actions between them.

(E)-4-Bromo-2-[(2-hydroxy-phen-yl)iminiometh-yl]phenolate.

Project description:The title compound, C(13)H(10)BrNO(2), crystallizes in a zwitterionic form. The zwitterion exists in a trans configuration about the C=N bond and is almost planar, the dihedral angle between the two benzene rings being 2.29?(9)°. An intra-molecular N-H?O hydrogen bond formed between the iminium NH(+) and the phenolate O(-) atoms generates an S(6) ring motif. In the crystal, the zwitterions are linked through O-H?O hydrogen bonds into chains along [101] and these chains are further connected through C-H?Br inter-actions into a two-dimensional network perpendicular to (101). C?C [3.572?(3)-3.592?(3)?Å] and C?Br [3.5633?(19)-3.7339?(18)?Å] short contacts are observed. The crystal studied was a twin with twin law 00, 00, 001 with a domain ratio of 0.09919?(2):0.90081?(2).

Crystal structure of ({4-[(4-bromo-phen-yl)ethyn-yl]-3,5-di-ethyl-phen-yl}ethyn-yl)triiso-propyl-silane.

Project description:The title compound, C29H37BrSi, was synthesized by the Sonogashira coupling of [(3,5-diethyl-4-ethynylphen-yl)ethyn-yl]triiso-propyl-silane with 4-bromo-1-iodo-benzene. In the structure, the two phenyl rings are nearly parallel to each other with a dihedral angle of 4.27?(4)°. In the crystal, ?-? inter-actions between the terminal and central phenyl rings of adjacent mol-ecules link them in the a-axis direction [perpendicular distance = 3.5135?(14); centroid-centroid distance = 3.7393?(11)?Å]. In addition, there are weak C-H?? inter-actions between the isopropyl H atoms and the phenyl rings of adjacent mol-ecules.

Crystal structure of 2-(4-chloro-phen-yl)-2-oxoethyl 3-bromo-benzoate.

Project description:2-(4-Chloro-phen-yl)-2-oxoethyl 3-bromo-benzoate, C15H10BrClO3, was synthesized in a single-step reaction by condensation of 3-bromo-benzoic acid with 2-bromo-1-(4-chloro-phen-yl)ethanone in di-methyl-formamide in the presence of tri-ethyl-amine as a catalyst. The structure consists of an aryl ketone moiety linked to an aryl ester unit by a methyl-ene group. Both units are reasonably planar (r.m.s. deviations of 0.119 and 0.010?Å for the aryl ketone and aryl ester units, respectively) and are almost orthogonal, with an angle of 88.60?(3)° between them. In the crystal, mol-ecules form five separate sets of inversion dimers. Three of these are generated by two C-H?O inter-actions and a C-H?Br contact, and form chains along c and along the ab cell diagonal. In addition, two inversion-related ?-? stacking inter-actions between like aryl rings again form chains of mol-ecules but in this instance along the bc diagonal. These contacts generate infinite layers of mol-ecules parallel to (011) and stack the mol-ecules along the a-axis direction.
