(E)-2-Hydroxy-6-[(4-propylphenyl)iminiomethyl]phenolate
Özet
The title compound, C(16)H(17)NO(2), crystallizes with three crystallographically independent zwitterionic molecules in the asymmetric unit which differ significantly in the orientations of the propyl side chains. The dihedral angles between the two benzene rings in the three molecules are 6.17 (7), 6.75 (7) and 23.67 (7)degrees, respectively. In each independent molecule, an intramolecular N-H center dot center dot center dot O hydrogen bond generates an S(6) ring motif. In the crystal, each independent molecule exists as part of an O-H center dot center dot center dot O hydrogen-bonded centrosymmetric R(2)(2) (10) dimer.
