14-Bromo-12-chloro-2,16-dioxapentacyclo[7.7.5.01,21.03,8.010,15]henicosa-3(8),10,12,14-tetraene-7,20-dione
In the title compound, C19H16BrClO4, both the fused xanthene rings and one of the cyclo-hexane rings adopt envelope conformations, while the other cyclo-hexane ring is in a chair conformation. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming infinite chains running along [10-1] incorporating R 2 (2)(16) ring motifs. In addition, C-H⋯π inter-actions and weak π-π stacking in...
متن کامل3-(3-Bromo-4-methoxyphenyl)-1,5-diphenylpentane-1,5-dione
In the title compound, C(24)H(21)BrO(3), the central bromo-methoxy-benzene ring forms dihedral angles of 63.6 (1) and 60.3 (1)° with the terminal phenyl rings, while the angle between the two phenyl rings is 25.8 (1)°. The crystal structure is stabilized by weak C-H⋯Br and C-H⋯O hydrogen bonds, and C-H⋯π and π-π stacking [centroid-centroid distance = 3.910 (3) Å] inter-actions.
متن کامل2-Bromo-1,3-diphenylpropan-1,3-dione
The title compound, C(15)H(11)BrO(2), exists as a diketone in which the two benzoyl groups are nearly perpendicular to each other [dihedral angles = 79.9 (1) and 87.4 (1)° in the two independent mol-ecules].
متن کامل3-(6-Bromo-4-oxo-4H-chromen-3-yl)-3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dione
The mol-ecular structure of the title compound, C(16)H(11)BrN(2)O(4)S, is very similar to that of the previously reported fluoro analogue [al-Rashida et al. (2010 ▶). Acta Cryst. E66, o2707]. The mean planes of the bicyclic chromone system and the benzene ring of the benzothia-diazine derivative make a dihedral angle of 58.23 (8)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, ...
متن کامل6-Bromo-1-butylindoline-2,3-dione
There are two independent mol-ecules in the asymmetric unit of the title compound, C(12)H(12)BrNO(2). The C-C bond lengths of the two carbonyl C atoms of the five-membered rings are distinctly longer than a normal Csp(2)-Csp(2) single bond. One of the mol-ecules makes parallel self-coupled (inversion) dimers by π-π inter-actions with phen-yl-phenyl inter-planar distances of 3.403 (2) Å. The oth...
