In the title compound, C(18)H(20)O(4)S, the thio-phene and benzene rings are oriented at a dihedral angle of 10.83 (11)°. The central chain makes dihedral angles of 1.86 (13) and 9.25 (12)° with the benzene and thio-phene rings, respectively. In the crystal, mol-ecules are linked through weak inter-molecular C-H⋯O inter-actions. π-π inter-actions are also observed between the benzene rings with a centroid-centroid distance of 3.6832 (12) Å.

Project description:Mol-ecules of the title amino-chalcone, C(18)H(19)NO(4), are twisted, with a dihedral angle of 11.26?(6)° between the 4-amino-phenyl and 2,4,5-trimeth-oxy-phenyl rings. The conformations of the three meth-oxy groups with respect to the benzene ring are slightly different. Two meth-oxy groups are almost coplanar with the attached benzene ring [C-O-C-C torsion angles of -1.45?(19) and 1.5?(2)°], while the third is (-)-synclinal with the attached benzene ring [C-O-C-C = -81.36?(17)°]. In the crystal structure, mol-ecules are stacked into columns along the b axis and mol-ecules in adjacent columns are linked by N-H?O hydrogen bonds into V-shaped double columns. Weak ?-? inter-actions are also observed, with a centroid-centroid distance of 3.7532?(8)?Å.

(E)-1-(2-Hy-droxy-phen-yl)-3-(2,4,5-trimeth-oxy-phen-yl)prop-2-en-1-one.

Project description:In the title chalcone derivative, C(18)H(18)O(5), the dihedral angle between the hy-droxy-substituted benzene ring and the trimeth-oxy-substituted benzene ring is 16.3 (1)°. The three meth-oxy groups are essentially coplanar with the benzene ring to which they are attached, with an r.m.s. deviation of 0.0208 Å. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, weak C-H⋯O inter-actions link mol-ecules into helical chains along the b axis. These chains are connected into sheets parallel to the bc plane by further weak C-H⋯O inter-actions.

Project description:The asymmetric unit of the title compound, C(17)H(19)NOS, contains two independent mol-ecules which differ in the dihedral angles between the five- and six-membered rings [12.52?(10) and 4.63?(11)°].

Project description:In the title compound, C(15)H(14)O(2)S, the dihedral angle between the aromatic rings is 8.46 -(8)°. The central enone group is planar (r.m.s. deviation = 0.0267 Å) and is oriented at a dihedral angle of 1.20 (9)° with respect to the benzene ring and at 8.27 (9)° with respect to the thio-phene group. In the crystal, the mol-ecules are linked into polymeric chains extending along the b axis due to inter-molecular O-H⋯O hydrogen bonding.

(E)-1-(2-Thien-yl)-3-(2,4,5-trimethoxy-phen-yl)prop-2-en-1-one.

Project description:In the title mol-ecule, C(16)H(16)O(4)S, the enone fragment, thio-phene ring and benzene ring are individually essentially planar. The thio-phene ring is disordered over two sites, corresponding to a rotation of approximately 180° about the single C-C bond to which it is attached. The approximate ratio of occupancies for the major and minor components is 0.872 (2):0.128 (2). The major component of the thio-phene ring and the benzene ring are twisted from each other by 13.92 (19)°. An intra-molecular C-H⋯O hydrogen bond generates an S(5)S(5) ring motif. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen-bonding inter-actions. In addition, a π-π stacking inter-action, with a centroid-centroid distance of 3.852 (2) Å, and short S⋯O [2.9378 (12) Å] and O⋯O [2.5811 (16) Å] contacts are observed.
