چکیده
The title chiral photochromic Schiff base compound, C(16)H(17)NO(2), was synthesized from (R)-1-phenyl-ethyl-amine and 5-methoxy-salicylaldehyde. The mol-ecule of the title compound exists in the phenol-imine tautomeric form. The dihedral angle between the two aromatic rings is 62.61 (11)°. An intra-molecular O-H⋯N hydrogen bond with an O⋯N distance of 2.589 (2) Å is observed. The crystal packing is stabilized by C-H⋯π inter-actions involving the aromatic ring.

In the title Schiff base, C(15)H(13)Br(2)NO, the benzene and phenyl rings form a dihedral angle of 75.18 (13)°. The N=C bond length of 1.263 (6) Å is shorter than of the N-C bond [1.476 (5) Å], indicating a double bond. In the crystal, there is some pseudosymmetry. This occurs because most of the two mol-ecules are centrosymmetrically related. The mol-ecular structure is stabilized by intra-mol...
