4-[1-(4-Cyano-benz-yl)-1H-benzimidazol-2-yl]benzonitrile.

ABSTRACT: In the title compound, C(22)H(14)N(4), a new substituted benzimidazole, three inter-molecular C-H?N inter-actions link neighbouring mol-ecules into different dimers with R(2) (2)(12), R(2) (2)(8) and R(2) (2)(24) ring motifs. A fourth C-H?N inter-action links neighbouring mol-ecules along the c axis. There is also a short inter-molecular contact between the azomethine (C=N) segment of the benzimidazole ring and one of the C atoms of a neighbouring benzene ring [N?C = 3.191?(5), C?C = 3.364?(6)?Å], which links the mol-ecules along the a axis. The two cyano-benzene rings are almost perpendicular to each other, with an inter-planar angle of 87.70?(7)°. The dihedral angles between the mean planes of the benzimidazole ring and the two outer benzene rings are 36.27?(16) and 86.70?(16)°. In the crystal structure, mol-ecules are stacked down the a axis with centroid-centroid distances of 3.906?(2)-3.912?(2)?Å and inter-planar distances of 3.5040?(17) and 3.6235?(17)?Å.
