5,6-Dimethyl-2-(pyridin-2-yl)-1-[(pyri-din-2-yl)meth-yl]-1H-benzimidazole.

The title compound, C20H18N4, was obtained via the condensation of 4,5-di-methyl-benzene-1,2-di-amine 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 mol-ecule exhibits an S(6) C-H⋯N intra-molecular hydrogen-bond motif. In the crystal, C-H⋯N hydrogen bonds link pairs of mol-ecules related by a crystallographic inversion center, forming R 2 (2)(20) rings. Additional weak C-H⋯N hydrogen bonds result in C(9) chains parallel to [001].
