N-(2-Azaniumylethyl)carbamate monohydrate

Abstract

In the crystal structure of the title compound, C3H8N2O2·H2O, the organic mol­ecule exists as zwitterion with the carboxyl group deprotonated and the amino group protonated. In the crystal, the components are linked by O—H⋯O and N—H⋯O hydrogen bonds.

Structurally simple complexes of CO2

“…76 Later, the structure of the monohydrate was published and, as one might expect with additional hydrogen bond donors and acceptors available, it shows a more extensive hydrogen-bonding network. 77 Crystal structures of similar zwitterionic carbamates are known [78][79][80] and all of these feature some form of H-bonding to the carboxylate group.…”
