In the title compound, C(15)H(12)N(4)·H(2)O, the organic mol-ecule displays approximate non-crystallographic twofold symmetry: the dihedral angle between the benzimidazole ring systems is 81.37 (12)°. In the crystal, the components are linked by O-H⋯N hydrogen bonds, forming chains propagating in [101]. Aromatic π-π stacking [centroid-centroid separation = 3.595 (2) Å] helps to consolidate the structure.
在标题化合物C₁₅H₁₂N₄·H₂O中,有机分子呈现出近似的非晶体学二重对称性:苯并咪唑环系统之间的二面角为81.37 (12)°。在晶体中,各组分通过O—H⋯N氢键相连,形成沿[101]方向延伸的链。芳香π-π堆积作用(质心-质心间距 = 3.595 (2) Å)有助于巩固该结构。
