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.

摘要

在标题化合物C(15)H(15)N(3)O(2)的分子中,平面苯并咪唑环系[最大偏差 = 0.023 (2) Å]相对于呋喃环的二面角为74.21 (5)°。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,该结构通过平行咪唑环之间的π-π接触[质心-质心距离 = 3.726 (1) Å]和弱C-H⋯π相互作用得以稳定。
