Sparkes (2014): Structure, hydrogen bonding and thermal expansion of ammonium carbonate monohydrate <em>Acta Crystallographica B</em> <strong>70</strong>(6), 948-962 (doi:10.1107/S205252061402126X)</p> <p> </p> <p>The chain motif of alternating hydrogen-bonded carbonate and N1 ammonium ions parallel to the a-axis. Note that the N2 ammonium cations ‘decorate’ this chain, donating the sole hydrogen bond to the water molecule. This viewing direction corresponds with that shown in Figures 3a and 3b. Dashed rods depict hydrogen bonds.
