Synthesis, crystal structure and Hirshfeld surface analysis of (1H-benzimidazol-2-yl)(morpholin-4-yl)methane-thione.

The title compound, C12H13N3OS, was synthesized via the Willgerodt-Kindler method. The benzimidozole moiety is essentially planar (r.m.s. deviation = 0.0084 Å). The thio-amide group is inclined by 54.80 (14)° to the benzimidazole ring system. The morpholine ring is disordered over two sets of sites [ratio 0.841 (11):0.159 (11)], with chair conformations for both components. In the crystal, mol-ecules are linked into N-H⋯N hydrogen-bonded chains running parallel to the c axis. Hirshfeld surface analysis was used to qu-antify the inter-molecular inter-actions.
