چکیده
The title chiral photochromic Schiff base compound, C(21)H(19)N(3)O, was synthesized from (R)-1-phenyl-ethyl-amine and the salicylaldehyde of an azobenzene derivative. The mol-ecule corresponds to the phenol-imine tautomer, the C=N and N-C bond distances being 1.279 (3) and 1.477 (3) Å, respectively. An intra-molecular O-H⋯N hydrogen bond occurs. The diazenyl group adopts a trans form with an N=N distance of 1.243 (3) Å.

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...

A novel Schiff base compound, C(20)H(27)NO(2), was obtained by a condensation of rimantadine and 2-hy-droxy-4-meth-oxy-benzaldehyde. An intra-molecular O-H⋯N hydrogen bond supports the phenol-imine tautomeric form. The adamantane and imino-methyl-4-meth-oxy-phenol units are arranged in a folded conformation [C-N-C-C torsion angle = 110.9 (3)°]. In the crystal, highly hydro-phobic adamantane moi...
