2-Methyl-12H-benzimidazo[2,1-b][1,3]benzothiazin-12-one
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-(2-Methoxyphenyl)-9,9-dimethyl-8,9-dihydro-12H-benzo[a]xanthen-11(10H)-one
The title compound, C(26)H(24)O(3), was synthesized via the coupling of 2-methoxy-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 2-methoxy-phenyl ring is almost perpendic-ular to the plane through the four C atoms of the pyran ring [dihedral angle = 88.76 (9)°].
متن کامل12-(2-Hydroxy-6-oxocyclohex-1-enyl)-9,10-dihydro-8H-benzo[a]xanthen-11(12H)-one
In the xanthenone system of the title compound, C23H20O4, the pyran ring has a maximum deviation of 0.111 (1) Å from planarity and the outer cyclo-hexene ring exhibits a puckered conformation. The three methyl-ene C atoms of the cyclo-hexene ring bonded to the pyran unit are disordered over two sets of sites [occupancies = 0.570 (3) and 0.430 (3)]. In the crystal, mol-ecules are linked by C-H⋯O...

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...
متن کامل2-(2-Hydroxyethyl)phthalazin-1(2H)-one
In the mol-ecule of the title compound, C(10)H(10)N(2)O(2), the rings are nearly coplanar, making a dihedral angle of 2.35 (5)°. In the crystal structure, inter-molecular C-H⋯O, C-H⋯N and O-H⋯O hydrogen bonds link the mol-ecules, generating R(4) (4)(22) and R(4) (4)(24) ring motifs to form a three-dimensional network. A weak π-π inter-action between the pyridazinone and benzene rings further st...
