چکیده
In the title compound, C(16)H(9)F(4)N(3)O(2), the dihedral angle between the aromatic ring systems is 4.10 (14)° and a bifurcated intra-molecular N-H⋯(O,F) hydrogen bond generates an S(6) ring for the O-atom acceptor and an S(5) ring for the F-atom acceptor. A short C-H⋯O conact also occurs. In the crystal, mol-ecules are linked by C-H⋯O inter-actions.

In the title compound, C22H19N3O3S, the six-membered ring of the 1,2,3,4-tetra-hydro-naphthalene ring system adopts an envelope conformation with the central CH2 C atom as the flap. The mol-ecular conformation is stabilized by an S⋯O contact, forming a pseudo-five-membered ring. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds into chains propagating along [102].

In the title compound, C16H15N3O, the dihedral angle between the indole ring system (r.m.s. deviation = 0.020 Å) and the phenyl ring is 14.49 (9)°. The mol-ecular conformation is supported by an intra-molecular C-H⋯O inter-action, which closes an S(7) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R2(2)(8) loops.
