3,5-Dibromo-2,2,6,6,7,7-hexamethyloctane-4-one
In the title mol-ecule, C14H26Br2O, the central carbonyl group (C3O) is essentially planar (r.m.s. deviation = 0.0021 Å). The Br atoms lie on the same side of the mol-ecule and are approximately syn, with a Br-C⋯C-Br torsion angle of -43.52 (13)°. The crystal structure is devoid of any specific inter-molecular inter-actions.
متن کامل4-(2,6-Dibromo-4-fluoroanilino)pent-3-en-2-one
The title enamino-ketone, C(11)H(10)Br(2)FNO, has a roughly planar pentenone chain; the maximum displacement of an atom from the pentenone plane is 0.071 (4) Å. The dihedral angle between the benzene ring and the pentenone unit is 77.2 (1)°. Inter-molecular C-H⋯Br and C-H⋯O inter-actions, as well as an intra-molecular N-H⋯O inter-action, are observed. In both methyl groups, each H atom is disor...

In the title compound, C(15)H(10)Br(2)Cl(2)O, the terminal benzene rings make a dihedral angle of 31.1 (2)° with each other. In the crystal, mol-ecules are stacked along the a axis and consolidated by C-H⋯π inter-actions. Short Cl⋯Cl [3.1140 (17) Å] and Br⋯Cl [3.4565 (13) Å] contacts are observed.

In title compound, C(12)H(11)Br(2)NO(2), the coumarin ring system is almost planar, the two rings being inclined to one another by 1.40 (15)°. There are two short intra-molecular inter-actions (N-H⋯Br and C-H⋯Br) involving the Br atoms. In the crystal, mol-ecules stack along the a-axis direction via π-π inter-actions; the centroid-centroid distances vary from 3.6484 (19) to 3.7942 (19) Å.
متن کامل2,3-Dibromo-1,3-bis(4-fluorophenyl)propan-1-one
In the title compound, C(15)H(10)Br(2)F(2)O, the dihedral angle between the two 3-fluoro-substituted benzene rings is 5.7 (5)°. The two bromine substituents on the chalcone moiety are close to anti as the Br-C-C-Br torsion angle is 176.9 (7)°. Weak C-Br⋯π inter-actions may contribute to the crystal stability.
