Network of C-H...O interactions in 4-benzyloxy-3-methoxybenzaldehyde (vanillin benzyl ether).

The title aldehyde, C15H14O3, crystallized in the centrosymmetric space group P2(1)/c with one molecule in the asymmetric unit. Six significant intermolecular C-H...O interactions have C...O distances ranging from 3.405 (2) to 3.802 (2) A and C-H...O angles ranging from 121 to 162 degrees. These six intermolecular interactions link a molecule directly to six neighbors and form a three-dimensional network. The dihedral angle between the best-fit planes of the benzene rings within a molecule is 78.1 (1) degrees. The dihedral angle between the carboxaldehyde-group plane and the best-fit plane of the ring to which it is attached is 3 (1) degrees.
