Bis(2-bromo-5-methyl-phen-oxy)methane.

Project description:The complete mol-ecule of the title compund, C(15)H(14)Br(2)O(2), is generated by the application of crystallographic twofold symmetry, with the central C atom lying on the rotation axis. The dihedral angle between the benzene rings is 62.4 (3)°. In the crystal, short Br⋯Br contacts [3.4885 (16) Å] occur.

Bis(3-bromo-methyl-2-meth-oxy-1-naphth-yl)methane.

Project description:The title compound, C(25)H(22)Br(2)O(2), crystallizes with two mol-ecules in the asymmetric unit.

9-(2-Bromo-phen-oxy-carbon-yl)-10-methyl-acridinium trifluoro-methane-sulfonate.

Project description:In the crystal structure of the title compound, C(21)H(15)BrNO(2) (+)·CF(3)SO(3) (-), adjacent cations are linked through C-Br⋯π and π-π contacts [centroid-centroid distance = 3.744 (2) Å], and neighbouring cations and anions via C-H⋯O, C-F⋯π and S-O⋯π inter-actions. The acridine and benzene ring systems are oriented at a dihedral angle of 18.7 (1)°. The carb-oxy group is twisted at an angle of 69.3 (1)° relative to the acridine skeleton. The mean planes of adjacent acridine moieties are either parallel or inclined at an angle of 27.8 (1)° in the lattice.

(2E)-3-(3-Bromo-4-meth-oxy-phen-yl)-1-(4-methyl-phen-yl)prop-2-en-1-one.

Project description:The overall shape of the mol-ecule of the title compound, C(17)H(15)BrO(2), can be described by the dihedral angles between three planar fragments: 1-bromo-2-meth-oxy-phenyl ring [maximum deviation = 0.003 (2) Å], the central prop-2-en-1-one chain [maximum deviation = 0.005 (2) Å], and the methyl-phenyl ring [maximum deviation = 0.004 (2) Å]. The terminal planes are twisted by 10.37 (12)°, while the central plane is almost coplanar with the methyl-phenyl ring [3.30 (13)°], but the dihedral angle with the other phenyl ring is significantly larger [8.76 (16)°]. In the crystal, mol-ecules are linked into chains along [001] by three C-H⋯O hydrogen bonds. These chains inter-act with each other by means of weak π-π contacts [centroid-centroid distances = 3.73 (1) and 3.44 (1) Å]. An inter-molecular C-H⋯Br inter-action also occurs.

1,4-Bis[2-(prop-1-en-yl)phen-oxy]butane.

Project description:The mol-ecule of the title compound, C(22)H(26)O(2), exhibits C(i) mol-ecular symmetry with a crystallographic inversion centre at the mid-point of the central C-C bond. A kink in the mol-ecule is defined by the torsion angle of 66.7?(2)° about this central bond of the alkyl bridge.

Methyl (2Z)-2-bromo-methyl-3-(2,4-dichloro-phen-yl)prop-2-enoate.

Project description:In the title compound C11H9BrCl2O2, which represents the Z isomer, the methyl-acrylate moiety is essentially planar within 0.039 (2) Å and has an extended trans configuration. The benzene ring makes a dihedral angle of 28.3 (1)° with the mean plane of the methyl-acrylate moiety. The crystal packing is characterized by C-H⋯O hydrogen bonding and halogen-halogen inter-actions [Cl⋯Cl = 3.486 (3) Å], resulting in the formation of R 2 (2)(11) ring motifs and connecting the mol-ecules into chains propagating along the b axis.
