(E,E)-N,N-Bis(2,6-difluoro-benzyl-idene)butane-1,4-diamine
Abstract:
The asymmetric unit of the title compound, C(18)H(16)F(4)N(2), comprises two half crystallographically independent potentially bidentate Schiff base ligands, with an inversion centre located at the mid-point of the central C-C bond. The crystal packing is stabilized by inter-molecular C-H⋯F and π-π inter-actions [centroid-centroid distance = 3.8283 (11) Å].
