The asymmetric unit of the title xanthene compound, C(25)H(30)O(5), contains two mol-ecules in which the pyran ring and the dimeth-oxy-phenyl ring are nearly perpendicular to one another [dihedral angles = 86.81 (8) and 84.45 (9)°]. One of the meth-oxy groups in one mol-ecule is twisted away from the phenyl ring [C-O-C-C torsion angle = -103.40 (16)°]. The pyran ring adopts a boat conformation ...

In the title compound, C(24)H(20)ClF(2)N(3)O(3)S, the essentially planar triazole ring (r.m.s. deviation = 0.001 Å) forms dihedral angles of 22.35 (10), 68.17 (10) and 42.01 (10)° with the mean planes of the trimeth-oxy-phenyl, chloro-phenyl and difluoro-phenyl rings, respectively. A weak intra-molecular C-H⋯π inter-action occurs. In the crystal, mol-ecules are linked into sheets lying parallel...

The title compound, C(16)H(16)N(2)OS(2), was obtained from a condensation reaction of benzyl dithio-carbazate and 4-meth-oxy-benzaldehyde. In the mol-ecule, the meth-oxy-phenyl ring and dithio-carbazate fragment are located on opposite sides of the C=N double bond, showing an E configuration. The dithio-carbazate fragment is approximately planar (r.m.s. deviation = 0.0052 Å); its mean plane is ...

The title compound, C(18)H(11)N(2)O(+)·Cl(-)·H(2)O, was prepared by the reaction of 1,8-naphthalic anhydride with o-phenyl-ene-diamine in DMF. The dihedral angle formed by the phenyl and naphthalic rings is 177.06°. The structure is stabilized by intra-molecular C-H⋯O hydrogen bonds. There are N-H⋯Cl, O-H⋯Cl, C-H⋯O and C-H⋯Cl hydrogen bonds in the structure.

In the title compound, C(32)H(32)N(2)O(2)S, the pyrrolidine ring adopts a twist conformation while the tetra-hydro-pyridine ring is in a distorted half-chair conformation. The two rings are trans-fused. The dihedral angle between the sulfonyl and benzyl phenyl rings is 72.54 (14)°. The mol-ecular structure is stabilized by C-H⋯O hydrogen bonds, and N-H⋯π inter-actions involving the benzyl pheny...
