4-Nitro-2-{(tricyclo­3.3.1.137decan-1-yl)iminium­ylmeth­yl}phenolate

摘要

The title compound, C17H20N2O3, 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 intra­molecular N—H⋯O hydrogen-bond inter­action between the iminium N atom and the phenolate O atom.
