The bis-(benzimidazol-1-yl)methane mol-ecule of the title compound, C(15)H(12)N(4)·2H(2)O, displays a trans conformation with a twofold axis running through the methylene C atom. Two adjacent water mol-ecules are bonded to this mol-ecule through O-H⋯N hydrogen bonds, forming a trimer. Adjacent trimers are connected together via C-H⋯O inter-actions, forming a chain running along the b-axis direction. Two such chains are joined together via π-π inter-actions [centroid-centroid distance = 3.556 (2) Å], forming double chains, which are connected via the water mol-ecules through C-H⋯O associations, forming a sheet structure. The sheets are stacked on top of each other along the a-axis direction and connected through O-H⋯O and C-H⋯O inter-actions, forming a three-dimensional ABAB layer network structure.
标题化合物C(15)H(12)N(4)·2H(2)O的双（苯并咪唑-1-基）甲烷分子呈反式构象，有一个二重轴穿过亚甲基C原子。两个相邻的水分子通过O-H⋯N氢键与该分子相连，形成三聚体。相邻的三聚体通过C-H⋯O相互作用连接在一起，形成沿b轴方向延伸的链。两条这样的链通过π-π相互作用[质心-质心距离 = 3.556 (2) Å]连接在一起，形成双链，双链通过水分子经C-H⋯O缔合连接，形成层状结构。这些层沿着a轴方向相互堆叠，并通过O-H⋯O和C-H⋯O相互作用连接，形成三维ABAB层状网络结构。
