Acta Crystallogr E Crystallogr Commun. 2019 Apr 18;75(Pt 5):646-649. doi: 10.1107/S2056989019005103. eCollection 2019 May 1.

Abstract

The title compound, C15H15NO4·C3H7NO·H2O, a secondary amine mol-ecule, is accompanied by one equivalent of water and one equivalent of di-methyl-formamide (DMF) as solvents. The mol-ecule is non-planar, with a Car-yl-CH2-NH-Car-yl torsion angle of -66.3 (3)°. In the crystal, O-H⋯O and N-H⋯O hydrogen-bonding inter-actions between the amine mol-ecules and the two types of solvent mol-ecule result in the formation of a layered structure extending parallel to (010).

Keywords: 2-hy­droxy-3-meth­oxy-benzaldehyde; 4-amino­benzoic acid (PABA); crystal structure; di­methyl­formamide solvate; hydrogen bonding; secondary amine; vanillin derivative.
