Crystal structure of a new 2,6-bis(imino)pyridine derivative: (1E,1′E)-1,1′-(pyridine-2,6-diyl)bis[N-(4-chlorophenyl)ethan-1-imine]

Abstract

The asymmetric unit of the title compound, C21H17Cl2N3, contains two crystallographically independent molecules (A and B). Both molecules have E configurations for both imine double bonds with regard to the aryl and pyridine groups. The conformations of the two molecules differ with the 4-chlorophenyl rings being inclined to the central pyridine ring by 77.64 (6) and 86.18 (6)° in molecule A, and 80.02 (5) and 43.41 (6)° in molecule B. In the crystal, molecules are linked by a number of C—H...π interactions, forming layers parallel to the bc plane.
