Project description:In the title compound, C(16)H(13)BrO(2), two benzene rings form a dihedral angle of 44.3?(9)°. In the crystal, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into chains propagating in [010]. The crystal packing also exhibits short Br?Br contacts of 3.4787?(8)?Å. A comparison of the DFT-optimized gas-phase mol-ecular geometry with that in the crystal structure revealed only small differences.

Project description:In the mol-ecules of the title compounds, (2E)-1-(3-bromo-thio-phen-2-yl)-3-(2-meth-oxy-phen-yl)prop-2-en-1-one, C14H11BrO2S, (I), which crystallizes in the space group P-1 with four independent mol-ecules in the asymmetric unit (Z' = 8), and (2E)-1-(3-bromo-thio-phen-2-yl)-3-(3,4-di-meth-oxy-phen-yl)prop-2-en-1-one, C15H13BrO3S, (II), which crystallizes with Z' = 8 in the space group I2/a, the non-H atoms are nearly coplanar. The mol-ecules of (I) pack with inversion symmetry stacked diagonally along the a-axis direction. Weak C-H?Br intra-molecular inter-actions in each of the four mol-ecules in the asymmetric unit are observed. In (II), weak C-H?O, bifurcated three-center inter-molecular inter-actions forming dimers along with weak C-H?? and ?-? stacking inter-actions are observed, linking the mol-ecules into sheets along [001]. A weak C-H?Br intra-molecular inter-action is also present. There are no classical hydrogen bonds present in either structure.

(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 ?-? contacts [centroid-centroid distances = 3.73?(1) and 3.44?(1)?Å]. An inter-molecular C-H?Br inter-action also occurs.
