The crystal structure of the title compound contains discrete [{Na(H2O)2}2(μ-H2O)2(μ-pzdo)]2+ (pzdo is pyrazine N,N′-dioxide) cations, tetraphenylborate anions and uncoordinating water and pzdo molecules, held together by various hydrogen-bonding and C—H⋯π and O—H⋯π interactions.
The title compound, C12H12N2O2·2C2H4O2, was prepared from 1,2-di-4-pyridylethane, acetic acid, and hydrogen peroxide. The 1,2-di-4-pyridylethane N,N′-dioxide molecule is located on an inversion center. π–π stacking interactions between neighboring 1,2-di-4-pyridylethane N,N′-dioxide molecules are observed with a centroid–centroid distance of 3.613 Å, an interplanar distance of 3.317 Å, and a slippage of 1.433 Å. O—H⋯O hydrogen-bonding interactions between 1,2-di-4-pyridylethane N,N′-dioxide and acetic acid molecules result in distinct hydrogen-bonded units made of one N-oxide and two acetic acid molecules. These units are then linked into a three-dimensional network through weaker C—H⋯O hydrogen-bonding interactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
