Crystal structures of pyridinemonocarboxylic acid peroxosolvates (original) (raw)

Russian Chemical Bulletin, 2013

Abstract

ABSTRACT The crystal structures of new peroxosolvates of the following pyridinemonocarboxylic acids were studied: picolinic 2-C5H4NCOOH·H2O2 (1), nicotinic 3-C5H4NCOOH·H2O2 (2), and isonicotinic 4-C5H4NCOOH·2H2O2 (3). In these compounds, the acids exist exclusively as zwitterions, as opposed to non-solvated crystals. In compounds 1–3, the hydrogen peroxide molecules form two donor hydrogen bonds and, in some cases, one additional acceptor hydrogen bond. Peroxosolvate 2 can be considered as a novel drug formulation of vitamin B3.
