Abstract
The crystal structure of 2-(N,N-dimethylaminomethyl)-4-nitrophenol, C9H12N2O3 has been determined by X-ray diffraction methods. The crystals are monoclinic;C2/c (No. 15),a=23.437(6),b=5.334(2),c=17.444(4) Å,β=119.90(5)°,Z=8. The structure was solved by direct methods, and refined to anR value of 0.032 for 1095 nonzero independent amplitudes. Molecules of the title compound are found to exist in a zwitterionic form. Differences in hydrogen bonding in solution and in the solid phase are discussed. In nonpolar and weakly polar solvents, intramolecular O-H⋯N hydrogen bonding is predominating. In the solid state, two N+-H⋯O− bonds related through an inversion center form a cyclic dimer.
