Isolation and structural characterization of the elusive 1:1 adduct of hydrazine and carbon dioxide

Abstract

A solid hydrazine was isolated as a crystalline powder by reacting aqueous hydrazine with supercritical CO 2. Its structure determined by single crystal X-ray diffraction shows a zwitterionic form of NH 3 +NHCO 2 -. The solid hydrazine is remarkably stable but is as reactive as liquid hydrazine even in the absence of solvents. © 2011 The Royal Society of Chemistry.
