(E)-1-(1,3-Benzodioxol-5-yl)-3-(3-bromophenyl)prop-2-en-1-one
In the title compound, C(16)H(11)BrO(3), the mol-ecules adopt an E configuration with respect to the C=C double bond of the propenone unit. The 13 non-H atoms of the benzodioxole and propenone units are approximately coplanar (r.m.s. deviation = 0.027 Å) and the bromo-benzene ring plane forms a dihedral angle of 10.8 (1)° to this plane. The structure is layered, with the mol-ecules forming a he...

In the title mol-ecule, C(14)H(9)BrO(3)S, the the prop-2-en-1-one (enone) fragment is close to planar [C-C-C-O = 2.5 (7)°] and it subtends dihedral angles of 12.5 (3) and 5.3 (4)° with respect to the thio-phene and benzene rings, respectively. The dihedral angle between the aromatic ring systems is 12.60 (18)°. Two C-H⋯O inter-actions help to consolidate the non-centrosymmetic crystal packing, ...

There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(29)H(30)N(2)O(5), each having an E conformation about the C=C double bond. The dihedral angles between the meth-oxy-benzene rings in the two mol-ecules are 71.39 (17) and 68.64 (17)°. In the crystal, mol-ecules are linked by C-H⋯O inter-actions.

In the title compound, C24H18N2OS, the pyridine and the two phenyl rings are oriented at dihedral angles of 10.1 (5), 71.7 (6) and 68.7 (5)°, respectively, to the central thio-phene ring. In the crystal, pairs of weak C-H⋯O hydrogen bonds link inversion-related mol-ecules, forming dimers. The dimers are linked by further weak C-H⋯O hydrogen bonds, forming chains running along the a-axis direction.

The mol-ecule of the title compound, C(16)H(11)BrO(3), is essentially planar with a maximum deviation of 0.178 (4) Å and the configuration of the keto group with respect to the olefinic double bond is typically s-cis. In the crystal structure, inter-molecular Br⋯O inter-actions [3.187 (3)Å] give rise to chains parallel to the b axis. Adjacent chains are further linked along the a axis by C-H⋯π ...
