Abstract

The redetermined structure of the title compound, C12H12N2S, was refined from low-temperature (100K) single-crystal X-ray diffraction data. Although achiral, the compound crystallizes in Sohncke space group P212121 in a chiral conformation distorted from idealized C2 symmetry and the dihedral angle between the phenyl groups is 72.01(7)°. In the extended structure, the NH2 substituents participate in N - H⋯S, N - H⋯N, and N - H⋯π interactions, leading to a three-dimensional hydrogen-bonded array. These results highlight the role of sulfur bridges in tuning packing interactions relevant to polymer design.
