4-Methoxybenzenecarbothioamide

Abstract

The asymmetric unit of the title compound, C8H9NOS, contains two independent mol-ecules with the meth-oxy groups oriented in opposite conformations. The mean planes of the carbothio-amide groups are tilted by 7.88 (15) and 11.16 (9)° from the mean planes of the benzene rings. In the crystal, the mol-ecules form dimers via intermolecular N - H⋯S inter-molecular hydrogen bonds, resulting in eight-membered rings of R 22(8) graph-set motif. The dimers are further linked by C - H⋯O hydrogen bonds into chains along the c axis. Adjacent chains inter-act through inter-molecular N - H⋯S hydrogen bonds, generating eight-membered rings of R 42(8) graph-set motif.
