Synthesis, crystal structures, and spectral characteristics of 2-ethoxy-3-hydroxy-4,6-dinitropyridine and diaquasodium bis(2-ethoxy-3-hydroxy- 4,6-dinitropyridinate)

The oxidative nitration of 2-amino-3-hydroxypyridine in the presence of rare-earth metal cations allocates 2-ethoxy-3-hydroxy-4,6-dinitropyridine (I) as one of the reaction products. Treating compound I with a sodium hydroxide solution gives diaquasodium bis(2-ethoxy-3-hydroxy-4,6-dinitropyridinate) (II). The molecular and crystal structures of I and II were studied. The compounds were characterized by spectroscopic methods (IR and electronic absorption spectroscopy). The acidic dissociation constant of compound I was evaluated. © 2009 Pleiades Publishing, Ltd.
