Crystal Structure of Naptalam

抄録

The crystal structure of Naptalam, which is a pre-emergent herbicide, has been determined. A tilted amide group connects two planar moieties, which make a stepwise conformation with a dihedral angle of 3.76(7)° from naphtyl and phenyl groups. The molecules correlated with 2₁-axis make a dimmer. The crystal structure is stabilized by an infinite-intermolecular hydrogen-bond and π-π interaction.
