3-[2-(2-Amino-1H-benzo[d]imidazol-1-yl)ethyl]-1,3-oxazolidin-2-one

Abstract

In the title compound, C12H14N4O2, the benzimidazole ring is almost planar (r.m.s. deviation = 0.03 Å), with the fused ring system slightly folded at the shared atoms, with a dihedral angle of 3.4 (1)°. The oxazolidinone ring displays a twisted conformation on the –CH2–CH2– bond and its mean plane makes a dihedral angle of 57.4 (1)° with the benzimidazole ring mean plane. In the crystal, molecules are linked by N—H...O and N—H...N hydrogen bonds, forming chains propagating along the a-axis direction. The chains are linked by C—H...O and C—H...N hydrogen bonds, forming a three-dimensional structure, which is reinforced by C—H...π interactions.
