The title compound, C24H24N2, is an enantiomerically pure bis-aldimine, which displays twofold crystallographic symmetry, with two C atoms of the central benzene ring lying on the symmetry axis. The imine group is slightly twisted from the benzene core, with a dihedral angle of 12.72 (16)° between the benzene ring and the C=N—C* plane. The terminal phenyl rings make an angle of 66.44 (4)° and are oriented in opposite directions with respect to the benzene ring. In the crystal, molecules interact weakly through a C—H⋯π interaction involving the phenyl rings, and form chains along the 21 screw-axis in the [100] direction.
La síntesis de una nueva bis-imina quiralmente pura, de fórmula C24H24N2, se llevó a cabo por síntesis directa, en ausencia de disolvente, y la caracterización estructural se realizó por difracción de Rayos X en monocristal. Los grupos imino tienen la configuración E, común en aldiminas secundarias con un grupo estorboso sustituyendo el átomo de nitrógeno. Las moléculas se empacan en el estado sólido sin formar contactos intermoleculares significativos, a diferencia de sistemas imínicos y bis-imínicos cercanos, donde grupos aromáticos extendidos generan interacciones estabilizantes en el estado cristalino.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
