Popis: | The title compound, C26H18F3N3O2S, a 2-methoxy-substituted derivative, is closely related to its 4-methyl- and 4-chloro-substituted analogues and yet displays no structural relationships with them. The thiophene ring is disorder free and the –CF3group exhibits disorder, respectively, in contrast and similar to that observed in the 4-methyl- and 4-chloro-substituted derivatives. The torsion angle which defines the twist of the thiophene ring is −69.6 (2)° (gauche) in the title compound, whereas it is anticlinal in the 4-methyl- and 4-chloro-substituted derivatives, with respective values of 99.9 (2) and 99.3 (2)°. The absence of disorder in the thiophene ring facilitates one of its ring C atoms to participate in the lone intermolecular C—H...O hydrogen bond present in the crystal, leading to a characteristicC(5) chain graph-set motif linking molecules related through glides along [010]. An intramoleculr C—H...N hydrogen bond also occurs. |
