Summary: | The monotonic compression of α-d-mannose differs from the behaviour of all other sugars investigated so far, which all undergo phase transitions at a significantly lower pressure than the 9 GPa achieved in the current study. This exceptional stability of the α-d-mannose structure has been connected with the presence of two symmetry-independent molecules, and an increased number of degrees of freedom allowing a better accommodation of strains between hydrogen-bonded molecules. The presence of C−H···O bonds accompanying the non-H-bonding O···O interactions additionally stabilizes the α-d-mannose structure. |
