title: (2Z)-2-Anilino-2-[oxido(phen-yl)iminio]-N-(2-pyrid-yl)acetamide methanol 0.425-solvate.
abstract: The title compound, C(19)H(16)N(4)O(2)·0.425CH(4)O, crystallizes with two formula units per asymmetric unit. Researching its crystal structure constitutes part of a study of the nature of inter-actions between the N(+)-O(-) group and the vicinal NH group. The nitrone group and methanol solvent mol-ecules are linked via four N-H⋯O and one O-H⋯O hydrogen bonds, with donor-acceptor distances of 2.603 (3)-2.730 (3) and 2.770 (3) Å, respectively. The crystal structure also involves two intermolecular N-H⋯N hydrogen bonds.
