Crystal structure of 4-({5-[(E)-(3,5-di­fluoro­phen­yl)diazen­yl]-2-hy­droxy­benzyl­idene}amino)-2,2,6,6-tetra­methyl­piperidin-1-ox­yl

The asymmetric unit of the title compound, C(22)H(25)F(2)N(4)O(2), contains two crystallographically independent mol­ecules. In one mol­ecule, the two benzene rings are oriented at a dihedral angle of 1.93 (10)° and in the other mol­ecule the corresponding dihedral angle is 7.19 (9)°. The piperidine rings in the two mol­ecules adopt a similar distorted chair conformation, and both have pseudo-mirror planes passing through the N—O bonds. An intra­molecular O—H⋯N hydrogen bond between the hy­droxy group and the imine N atom is observed in both mol­ecules. In the crystal, weak C—H⋯O and C—H⋯F hydrogen bonds, enclosing R (2) (2)(6) ring motifs, and weak π–π stacking inter­actions link the mol­ecules into a three-dimensional supra­molecular network, with centroid-to-centroid distances between the nearly parallel phenyl and benzene rings of adjacent mol­ecules of 3.975 (2) and 3.782 (2) Å.
