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.
在标题化合物C(16)H(17)N(3)O(2)的分子中，平面苯并咪唑环系[最大偏差 = 0.013 (1) Å]相对于呋喃环的二面角为75.32 (4)°。分子内C-H⋯O相互作用导致形成一个平面六元环[最大偏差 = 0.019 (15) Å]，该六元环相对于相邻呋喃环的二面角为1.91 (3)°。在晶体结构中，分子间C-H⋯N相互作用将分子连接成中心对称的R(2) (2)(18)二聚体。此外，该结构通过咪唑环之间的π-π接触[质心-质心距离 = 3.5307 (8) Å]和弱C-H⋯π相互作用得以稳定。
