In the title compound, C 23H 19Cl 2N 5OS, the triazole ring makes dihedral angles of 24.81 (18), 69.94 (19) and 35.68 (18)° with the dichlorophenyl, benzene and methoxyphenyl rings, respectively. An intramolecular N - H⋯N hydrogen bond occurs. In the crystal, inversion dimers linked by pairs of N - H⋯S hydrogen bonds occur. In addition, there are weak C - H⋯π interactions involving the dichlorophenyl and triazole rings.

In the title compound, C 17H 10F6N 4· H 2O, the pyridine ring is not coplanar with the quinoline ring system; the dihedral angle between the two planes is 21.3 (1)°. One of the trifluoro-methyl group is disordered over two orientations with occupancies of 0.70 (1) and 0.30 (1). The water molecule is disordered over two positions with occupancies of 0.76 (1) and 0.24 (1). In the crystal, the water molecule is linked to the main molecule via N-H⋯O and C-H⋯O hydrogen bonds, and inversion-related pairs are linked via O-H⋯N hydrogen bonds. In addition, a weak π-π interaction is observed between the pyridine ring and the pyridine ring of the quinoline unit, with a centroid-centroid distance of 3.650 (2) Å.

In the title compound, C14H11Cl2N5O, the plane of the 1H-imidazo[4,5-c] pyridine ring system [r.m.s. deviation = 0.087(19)Å] makes a dihedral angle of 4.87(10)° with the terminal phenyl ring. An intramolecular N - HN hydrogen bond stabilizes the molecular conformation. In the crystal, N - HO hydrogen bonds link the molecules into inversion dimers. These dimers are connected by π-π interactions between imidazole rings [shortest centroid-centroid distance = 3.4443(14)Å]. © Devaru et al. 2014.

In the title compound, C15H14BrNO3S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.034(2), and the morpholine ring adopts a chair conformation. The dihedral angle between best plane through the 2H-chromene ring system and the morpholine ring is 86.32(9). Intra-molecular C-HS hydrogen bonds are observed. In the crystal, inversion-related C-HS and C-HO inter-actions generate R 2 (2)(10) and R 2 (2)(8) rings patterns, respectively. In addition, the crystal packing features - inter-actions between fused benzene rings [centroid-centroid distance = 3.7558(12)].

In the title compound, C15H14FNO3S2, the 2H-chromene ring system is close to being planar (r.m.s. deviation = 0.024) and the morpholine ring adopts a chair conformation. The dihedral angle between the 2H-chromene ring system and the morpholine ring (all atoms) is 88.21(11). In the crystal, inversion dimers linked by pairs of very weak C-HF hydrogen bonds generate R 2 (2)(8) loops; C-HO hydrogen bonds connect the dimers into [010] chains. Weak aromatic - stacking inter-actions between the pyran rings of the chromene systems [centroid-centroid distance = 3.6940(16)] are also observed.
