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 paral Show more
