In the title compound, NCCH(2)C(6)H(4)CH(2)CN, the bond lengths and angles are within normal ranges. The benzene ring makes dihedral angles of 4.94 (8) and 77.04 (8)° with the C-C-C-N mean planes. Weak non-conventional C-H⋯N hydrogen bonds are effective in the stabilization of the crystal structure. The weak C-H⋯N contacts form anti-parallel chains running in the a + c direction, and ring systems with two N-atom acceptors and four H-atom donors.
