1,3-Bis(4-fluoro-phen-yl)-N,N'-(propane-1,3-diyl-idene)dihydroxyl-amine.


ABSTRACT: The title compound, C(15)H(12)F(2)N(2)O(2), crystallizes with two mol-ecules (A and B) in the asymmetric unit. Both aromatic rings of both mol-ecules are disordered over two orientations [occupancy ratios of 0.768?(3):0.232?(3) and 0.770?(3):0.230?(3) for mol-ecule A and 0.789?(3):0.211?(3) and 0.789?(3):0.211?(3) for mol-ecule B]. The dihedral angles between the planes of the major and minor components of the disordered aromatic rings are 72.0?(4) and 71.2?(4)° for mol-ecule A, and 70.2?(4) and 71.5?(2)° for mol-ecule B. In the crystal, both mol-ecules form inversion dimers with R(2) (2)(6) ring motifs via pairs of inter-molecular O-H?N hydrogen bonds. The dimers are linked, forming zigzag C(7) chains along the c axis. Weak C-H?? inter-actions help to consolidate the packing.
