-[2-(1,3-Dioxoisoindolin-2-yl)-1,3-thia-zol-4-yl]benzo-nitrile

摘要

The title iso-indole, C18H8N3O2S, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit whose geometrical features are similar. The benzo-nitrile ring is oriented at an angle of 2.1?(1)° (mol-ecule A) and 16.0?(1)° (mol-ecule B), with respect to the iso-indole ring system. In the crystal, A mol-ecules are linked via C—H?N hydrogen bonds, forming C(15) chains propagating along along the c axis. B mol-ecules are linked via C—H?O inter-actions, forming dimers with an R22(10) graph-set motif. C—H?O and C—H?N inter-actions, charcterized by R22(15) and R21(7) motifs, are observed between mol-ecules A and B.
