non-planar by rotation around the N-aryl bond, with the substituent in most cases lying s-E in relation to the N-aryl bond; intermolecular electrostatic interactions in the crystal rationalise the two examples in which an s-Z conformation is observed. A large interplanaranglebetween the benzazole and the N-aryl planes is associated with a small interplanaranglebetween the planes of the N-aryl group and
