title: Assembly of a two-dimensional layer structure with 1,4-bis(1H-benzimidazol-1-ylmethyl)benzene dihydrate via hydrogen bonds and pi-pi interactions.
abstract: In the title compound, C(22)H(18)N(4).2H(2)O, the organic fragment lies across a centre of inversion in the P2(1)/n space group. The water molecules form C(2)-type hydrogen-bonded chains which are linked to the 1,4-bis(1H-benzimidazol-1-ylmethyl)benzene molecules through O-H...N hydrogen bonds, forming sheets reinforced by pi-pi stacking interactions between the aromatic rings within the layers.
