An intra-molecular C-H?O inter-action generates an S(9) ring motif. In the crystal, mol-ecules are linked into a three-dimensional network by weak C-H?O and C-H?? inter-actions, and a ?-? inter-action with a centroid-centroid distance of 3.6527?(8)?Å.

In the title 1,5-diketone compound, C(22)H(22)O(5)S(2), the benzene ring makes dihedral angles of 41.51 (6) and 25.83 (6)° with the two thio-phene rings, while the dihedral angle between the thio-phene rings is 26.67 (7)°. An intra-molecular C-H⋯O inter-action generates an S(9) ring motif. In the crystal, mol-ecules are linked into a three-dimensional network by weak C-H⋯O and C-H⋯π inter-actions, and a π-π inter-action with a centroid-centroid distance of 3.6527 (8) Å. ...[more]

Project description:There are two crystallographically independent mol-ecules in the asymmetric unit of the title bis-chalcone derivative, C(23)H(26)O(7). The mol-ecules are unsymmetrical and almost planar: the dihedral angle between two benzene rings is 1.04?(7)° in one mol-ecule and 2.31?(7)° in the other. The central penta-1,4-dien-3-one fragment makes dihedral angles of 7.61?(7) and 6.82?(7)° with the two adjacent benzene rings in one mol-ecule, while the corresponding values are 7.85?(7) and 9.42?(6)° in the other. In both mol-ecules, the three meth-oxy groups of the two 2,4,6-trimeth-oxy-phenyl units are coplanar with the attached benzene rings [C-O-C-C- torsion angles of -1.5?(2), -7.2?(2) and 4.1?(2)° in one mol-ecule and -0.7?(2), -5.5?(2) and -0.6?(2)° in the other]. The mol-ecular conformations are stabilized by weak intra-molecular C-H?O inter-actions generating two S(6) ring motifs. In the crystal, mol-ecules are linked by weak inter-molecular C-H?O inter-actions into zigzag chains parallel to the c axis. The crystal structure is further stabilized by C-H?? inter-actions and ?-? inter-actions with centroid-centroid distances of 3.6433?(8)?Å.

Project description:In the title aza-flavanone, C(18)H(19)NO(4), an intra-molecular cyclization product of chalcone, the central heterocyclic ring is in an envelope conformation and the dihedral angle between the benzene rings is 51.03 (10)°.
