Abstract:
The title compound, C(17)H(20)N(2)O(3), is a Schiff base, which is found as a zwitterion in the solid state. The geometry around the iminium N atom indicates sp(2)-hybridization. The zwitterion shows a strong intra-molecular N-H⋯O hydrogen-bond inter-action between the iminium N atom and the phenolate O atom.
