1-Methyl-4-({5-[(4-methyl-phen-yl)sulfan-yl]pent-yl}sulfan-yl)benzene
Abstract:
There are two independent mol-ecules in the asymmetric unit of the title compound, C(19)H(24)S(2). In both mol-ecules, the aliphatic segment of the ligand is in an all-trans conformation: the -S-(CH(2))(5)-S-bridging chain is almost planar (r.m.s. deviation for all non-H atoms = 0.0393 and 0.0796 Å in the two mol-ecules) and maximally extended. Their mean planes form dihedral angles of 4.08 (6)/20.47 (6) and 2.22 (6)/58.19 (6)° with the aromatic rings in the two mol-ecules. The crystal packing is purely governed by weak inter-molecular forces.

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
