5-Meth-oxy-2-[(2-morpholinoeth-yl)-iminio-meth-yl]phenolate

Each of the two independent mol-ecules of the title comound, C(14)H(20)N(2)O(3), exists in the zwitterionic form as the imino N atoms are protonated. The =N-H unit forms an intra-molecular hydrogen bond to the negatively charged O atom, and also a weaker intermolecular N-H⋯O bond, the latter resulting in inversion dimers.
