Crystal structure of 2-[2-(benzyloxy)benzylidene]malononitrile

Abstract

In the title benzylidenemalononitrile derivative, C17H12N2O, the dihedral angles between the central benzene ring and the Y-shaped C=C(CN)2group (r.m.s. deviation = 0.006 Å) and the terminal benzene ring are 12.72 (8) and 37.60 (11)°, respectively. The Car—O—Csp3—Cartorsion angle is −174.52 (13)° and the major twist between the aromatic rings occurs about the Csp3—Carbond. 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.
