RESUMO
In the title compound, C13H12N2OS, the planes of the thio-phene and phenyl rings are nearly perpendicular to each other, making a dihedral angle of 86.42â (12)°. In the crystal, mol-ecules are linked by C-Hâ¯O hydrogen bonds, forming a helical chain along the b-axis direction.
RESUMO
In the title compound, C14H11FO2, the dihedral angles beteen the central C3O ketone residue and the fluoro- and hy-droxy-substituted benzene rings are 50.44â (9) and 12.63â (10)°, respectively. The planes of the benzene rings subtend a dihedral angle of 58.88â (9)° and an intra-molecular O-Hâ¯O hydrogen bond closes an S(6) ring. No directional inter-actions beyond van der Waals packing contacts were identified in the crystal structure.
RESUMO
In the title compound, C14H11FO2, the two benzene rings are not coplanar, with a dihedral angle of 57.45â (12)° between their planes. In the crystal, mol-ecules are linked by an O-Hâ¯O hydrogen bond, forming a 21 helical chain along the b axis.
RESUMO
In the title compound, C14H12O2, the benzene rings make a dihedral angle of 58.84â (12)°. In the crystal, mol-ecules are linked into chains along the b-axis direction by O-Hâ¯O hydrogen bonds. These chains are further linked by C-Hâ¯O hydrogen bonds, forming layers parallel to the bc plane.
RESUMO
In the mol-ecule of the title compound, C15H14O2, the dihedral angle between the benzene and phenyl rings is 61.27â (8)°. In the crystal, O-Hâ¯O and weak C-Hâ¯O hydrogen bonds link the mol-ecules into chains extending along the c-axis direction.
RESUMO
In the title compound, C(12)H(11)N(3)OS, the dihedral angle between the pyridine and thio-phene rings is 46.70â (9)° and the C-N-N-C torsion angle is 178.61â (15)°. In the crystal, inversion dimers linked by pairs of N-Hâ¯O hydrogen bonds generate R(2) (2)(8) loops.
RESUMO
In the title compound, C(9)H(7)NO, the benzene ring forms a dihedral angle of 3.98â (12)° with the pyrrole ring. In the crystal, N-Hâ¯O hydrogen bonds links the mol-ecules into chains which run parallel to [02-1].
