Abstract
The title compound crysallises in the orthorhombic system P212121 with cell constants a= 11·202, b= 3·934, c= 26·077 Å, and Z= 4. The crystal and molecular structures were determined by direct methods from 1524 intensities measured on a diffractometer, and refined anisotropically (except hydrogen) to R 0·082. The possible influence of the packing arrangement on the molecular conformation, which differs significantly from that of earlier reported benzylideneailines, is discussed.
