ABSTRACT In the mol-ecule of the title compound, C(16)H(17)N(3)O(2), the planar benzimidazole ring system [maximum deviation = 0.013 (1) Å] is oriented at a dihedral angle of 75.32 (4)° with respect to the furan ring. An intra-molecular C-H⋯O inter-action results in the formation of a planar six-membered ring [maximum deviation = 0.019 (15) Å], which is oriented at a dihedral angle of 1.91 (3)° with respect to the adjacent furan ring. In the crystal structure, inter-molecular C-H⋯N inter-actions link the mol-ecules into centrosymmetric R(2) (2)(18) dimers. In addition, the structure is stabilized by π-π contacts between the imidazole rings [centroid-centroid distance = 3.5307 (8) Å] and weak C-H⋯π inter-actions.

    ABSTRACT: In the mol-ecule of the title compound, C(15)H(15)N(3)O(2), the planar benzimidazole ring system [maximum deviation = 0.023 (2) Å] is oriented at a dihedral angle of 74.21 (5)° with respect to the furan ring. In the crystal structure, inter-molecular C-H⋯N inter-actions link the mol-ecules into centrosymmetric R(2) (2)(18) dimers. In addition, the structure is stabilized by π-π contacts between parallel imidazole rings [centroid-centroid distance = 3.726 (1) Å] and a weak C-H⋯π inter-action.

An intra-molecular C-H⋯O inter-action results in the formation of a six-membered ring having an envelope conformation. In the crystal structure, inter-molecular C-H⋯N inter-actions link the mol-ecules into centrosymmetric R(2) (2)(18) dimers.
