title: Crystal structure of 2-[2-(benz-yloxy)benzyl-idene]malono-nitrile.
abstract: In the title benzyl-idenemalono-nitrile derivative, C17H12N2O, the dihedral angles between the central benzene ring and the Y-shaped C=C(CN)2 group (r.m.s. deviation = 0.006 Å) and the terminal benzene ring are 12.72 (8) and 37.60 (11)°, respectively. The Car-O-Csp (3)-Car torsion angle is -174.52 (13)° and the major twist between the aromatic rings occurs about the Csp (3)-Car bond. Weak aromatic π-π stacking [centroid-centroid separation = 3.7784 (13) Å; slippage = 1.21 Å] between inversion-related pairs of the central benzene rings is observed in the crystal.
