โœฆ Synopsis


In the title compound, C 18 H 18 O 2 S 2 , there are two independent and conformationally similar molecules in the asymmetric unit. In one of the molecules, the dihedral angle between the two aromatic rings is 77.1 (2) , and in the other it is 78.2 (2) . The two independent molecules are linked by a C-Hร ร ร interaction.

In the title compound, C 18 H 18 O 4 , the molecule is slightly twisted with a dihedral angle of 17.49 (5) between the two benzene rings. All of the methoxy substituents lie almost in the planes of the benzene rings to which they are attached. The crystal structure is stabilized by intermolecular C-

In the title compound, C 22 H 17 NO, the dihedral angles between the central benzene ring and the two terminal phenyl rings are 48.20 (4) and 49.62 (4) , resulting in a substantially twisted molecular conformation. Weak C-Hร ร ร interactions help to consolidate the centrosymmetric crystal packing.
