3-Fluoro-12H-benzimidazo[2,1-b][1,3]benzothiazin-12-one
In the title compound, C(14)H(7)FN(2)OS, prepared by the reaction of 2-bromo-4-fluoro-benzoyl choride with 2-mercaptobenzimidazole, the four-membered fused-ring system is essentially planar [maximum deviation from the mean plane = 0.035 (2) Å]. The crystal packing is stabilized by weak inter-molecular π-π [minimum ring centroid-centroid separation = 3.509 (7) Å], weak C-F⋯π [F⋯centroid = 3.4464...

In the title compound, C(15)H(10)N(2)OS, prepared by the reaction of 2-iodo-5-methyl-benzoyl chloride with 2-mercaptobenzimidazole, the four-membered fused-ring system is essentially planar [maximum deviation from the least-squares plane = 0.137 (6) Å]. The crystal packing is stabilized by weak inter-molecular π-π inter-actions [minimum ring centroid separation = 3.536 (4) Å] and weak C-H⋯π int...
متن کامل12-(4-Chlorophenyl)-9,9-dimethyl-9,10-dihydro-8H-benzo[a]xanthen-11(12H)-one
The title compound, C(25)H(21)ClO(2), was synthesized via the three-component coupling of 4-chloro-benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. The pyran ring adopts a boat conformation, while the cyclo-hexenone ring is in an envelope conformation. The 4-chloro-phenyl ring is almost perpendicular to the pyran ring [dihedral angle = 87.39 (1)°]. In the crystal, mol-ecules ar...
متن کامل9,9-Dimethyl-12-(4-nitrophenyl)-9,10-dihydro-12H-benzo[a]xanthen-11(8H)-one
In the mol-ecular structure of the title compound, C(25)H(21)NO(4), the pyran ring adopts a flattened boat conformation, while the cyclo-hexenone ring is in an envelope conformation. The 4-nitro-phenyl ring is almost perpendicular to the pyran ring [dihedral angle = 89.39 (1)°]. In the crystal, mol-ecules are connected by inter-molecular C-H⋯O hydrogen bonds.
متن کامل9,9-Dimethyl-12-phenyl-8,9-dihydro-12H-benzo[a]xanthen-11(10H)-one
The title compound, C(25)H(22)O(2), was synthesized via the three-component coupling of benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by pairs of inter-molecular C-H⋯O hydrogen bonds. The dimers are further connected into a three-dimensional network by π-π aromatic stacking inter-actions ...
