9-(Thio­phen-2-yl)-8,9-dihydro-3H-pyrazolo­[4,3-f]quinolin-7(6H)-one ethanol monosolvate

In the title compound, C(14)H(11)N(3)OS·C(2)H(5)OH, the dihedral angle between the pyridine N—C(fused)—C(fused)—C(thio­phene) plane and the plane of the thio­phene ring is 81.9 (3)°, indicating that they are close to perpendicular. The dihedral angle between this pyridine plane and the benzene ring...

description In the title compound, C(14)H(11)N(3)OS·C(2)H(5)OH, the dihedral angle between the pyridine N—C(fused)—C(fused)—C(thio­phene) plane and the plane of the thio­phene ring is 81.9 (3)°, indicating that they are close to perpendicular. The dihedral angle between this pyridine plane and the benzene ring is 1.3 (3)°. The thio­phene ring is disordered over two coplanar orientations with an occupancy ratio of 0.692 (7):0.308 (7), while the ethanol solvent mol­ecule is also disordered over two sets of site in a 0.66 (4):0.34 (4) ratio. In the crystal, chains are formed along the b axis by N—H⋯O and O—H⋯N inter­actions with adjacent chains being connected through C—H⋯N and C—H⋯S inter­actions.
