4,4-Dimethyl-1-(3-nitrophenyl)pent-1-en-3-one
All the non-hydrogen atoms except one methyl C atom of the title compound, C(13)H(15)NO(3), lie on a crystallographic mirror plane perpendicular to the b axis. The crystal packing is stabilized by two weak inter-molecular C-H⋯O hydrogen bonds.

In the title compound, C(16)H(16)O(2)S, the central propenone group is almost planar (r.m.s. deviation = 0.009 Å) and subtends dihedral angles of 8.55 (8) and 16.22 (8)° to the 2-meth-oxy-phenyl and 2,5-dimethyl-thio-phene residues, respectively. The dihedral angle between the ring systems is 23.47 (5)°. In the crystal, mol-ecules are linked by weak C-H⋯π inter-actions and aromatic π-π stacking...

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...

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)°]. Weak inter-molecular C-H⋯O hydrogen bonds link the two independent mol-ecules into pseudocentrosymmetric dimers. In one mol-ecule, the O atom of the carbonyl group is disordered over two positions ...

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 ...
