It is a colorless solid. Structure and reactionsThe structure of this salt was verified by X-ray crystallography. The respective C−O and C−N distances are 1.174(8) and 1.192(7) Å, consistent with the O=C=N− description. NH4+ forms hydrogen bonds to N, not O.[1] The compound is notable as the precursor in the Wöhler synthesis of urea, an organic compound, from inorganic reactants.[2]
