Structural Features of 2-Nitroguanidine
Abstract
The crystal and molecular structure of solid nitroguanidine (NO) was refined using x-ray single-crystal diffraction methods. Previous structure determinations yielded values for the imino C-N bond that either equaled or exceeded the amino C-N single bond lengths, but these data were neither precise nor particularly accurate. This study was undertaken to obtain more precise and accurate structural parameters. The experimental structural parameters of crystalline NQ are compared to the theoretical structural parameters of the isolated NO molecule. This investigation confirms that the C-N bond anomaly was real. However, it is concluded that the anomaly in the C-N bonds in crystalline NO is a result of the strong intermolecular hydrogen bond forces and to a lesser extent the intermolecular forces in the NO crystal structure. It is also concluded that these same intermolecular hydrogen bond forces are responsible for the enhanced insensitivity of NO to impact.
