title: 2-(1,3-Dibenzyl-imidazolidin-2-yl-idene)malononitrile.
abstract: In the title mol-ecule, C(20)H(18)N(4), the imidazolidine ring makes dihedral angles of 86.74 (2) and 81.18 (3)° with the two phenyl rings. In the absence of classical inter-molecular inter-actions, the crystal packing is stabilized by van der Waals forces.
