5,6-Dimethyl-2-(pyridin-2-yl)-1-[(pyri­din-2-yl)meth­yl]-1H-benzimidazole

The title compound, C₂₀H₁₈N₄, was obtained via the condensation of 4,5-di­methyl­benzene-1,2-di­amine with pyridine-2-carbaldehyde. The plane of the 2-(pyridin-2-yl) substitutent is canted by 2.75 (11)° from the plane of the benzimidazole system. The mol­ecule exhibits an S(6) C—H...N intra­molecular hydrogen-bond motif. In the crystal, C—H...N hydrogen bonds link pairs of mol­ecules related by a crystallographic inversion center, forming R₂²(20) rings. Additional weak C—H...N hydrogen bonds result in C(9) chains parallel to [001].
