Planar (r.m.s. deviation from the plane through all non-H atoms = 0.036 Å) mol-ecules of the title compound, C(16)H(11)BrO(2), form a layered structure stabilized by C-H⋯O hydrogen bonds and π-π stacking inter-actions.
متن کامل3,5,7-Trimethoxy-2-(4-methoxyphenyl)-4H-1-benzopyran-4-one
In the title compound, C(19)H(18)O(6), also known as 3,4',5,7-tetra-methoxy-flavone, the dihedral angle between the benzopyran-4-one group and the attached benzene ring is 11.23 (8)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (01) by inter-molecular C-H⋯O hydrogen bonds, which generate R(...
متن کاملSynthesis and Bioevaluation of 4-[(2/4-chloro-/2, 3-dichloro-/2/4-bromo-/2, 4-dinitro-/4-nitrophenyl) Anilinomethyl]-6-t-butyl-2H-1-benzopyran-2-ones
Synthesis of 4-[(2/4-chloro-/2,3-dichloro-/2/4-bromo-/2,4-dinitro-/4-nitrophenyl) anilinemethyl]6-t-butyl-2H-1-benzopyran-2-ones have been carried out. Synthesized compounds were characterized by 1HNMR, IR and other physical and analytical data. All of the synthesized compounds were evaluated for their antifungal activity against Aspergillus awamori and Sclerotium rolfsii and antibacterial acti...
متن کامل(E)-3-[2-(4-Chlorophenylsulfonyl)vinyl]-6-methyl-4H-chromen-4-one
In the title compound, C(18)H(13)ClO(4)S, the mean planes of the chloro-phenyl ring and the S-C=C-C chain are oriented at angles of 52.7 (2) and 51.3 (2)°, respectively, with respect to the sulfonyl (O=S=O) plane. The dihedral angle between the mean planes of the chloro-phenyl group and the benzopyran ring is 80.7 (1)°. The crystal structure is stabilized by two inter-molecular C-H⋯O inter-acti...

The title co-crystal, 0.95C(20)H(20)O(3)·0.05C(20)H(19)ClO(3), arises as the chloride carried over during the synthesis shares a position with an aromatic H atom; the partial occupancies are 0.947 (2) and 0.053 (2) for H and Cl, respectively. The mol-ecular structure is stabilized by intra-molecular C-H⋯O contacts, forming pseudo five- and six-membered rings with S(5) and S(6) graph-set motifs,...
