Crystal structures of 1-Hydroxyimidazole and its salts

Abstract

The crystal structures of 1-hydroxyimidazole and four protic salts (chloride, bromide, sulfate, nitrate) thereof were determined. The molecular geometries (bond lengths and angles) of the free base and the salts were compared. Hydrogen bonding patterns were studied, and OH⋯N, OH⋯Cl, OH⋯Br, OH⋯O, NH⋯Cl, NH⋯Br, and NH⋯O interactions were identified. Hirshfeld surface analysis gave quantitative insight into these interactions. © 2011 by the authors; licensee MDPI, Basel, Switzerland.
