5-Methoxy-1H-Benzo[d]imidazole-2(3H)-Thione

Abstract

The title compound, C8H8N2OS, is stabilized by inter-molecular N - H⋯O and N - H⋯S hydrogen bonds and by π-π inter-actions. The hydrogen bonds generate a two-dimensional network with edge-fused centrosymmetric [R 2 2(8)R 4 4(20)R 2 2(8)] motifs, and these networks are connected by the π-π inter-actions. These π-π interactions occur between the homoaromatic rings of the molecules at ( ) and ( ); the centroid-centroid distance is 3.658 (1) Å and the plane-plane separation is 3.321 Å. The mol-ecule is approximately planar, with a dihedral angle of 1.58 (13)° between the two rings. © International Union of Crystallography 2007.
