Crystal structure of a new 2,6-bis-(imino)-pyridine derivative: (1E,1'E)-1,1'-(pyridine-2,6-di-yl)bis-[N-(4-chloro-phen-yl)ethan-1-imine].

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