title: Crystal structure of (E)-N1-[(anthracen-9-yl)methyl-idene]-N4-phenyl-benzene-1,4-di-amine.
abstract: The title compound, C27H20N2, a Schiff base synthesizedviaa condensation reaction between anthracene-9-carbaldehyde andN-phenyl-p-phenyl-enedi-amine, crystallizes with three independent mol-ecules in the asymmetric unit. The three mol-ecules have slightly varying overall conformations, all havingtransconformations with respect to the C=N bond. In the crystal, the packing features N-H⋯N hydrogen bonds, which connect mol-ecules into chains extending along thec-axis direction, inter-linked by C-H⋯π inter-actions (minimum H⋯Cg= 2.65 Å) into sheets lying parallel to (001).
