Figure 2
O—H⋯O intermolecular bond scheme in levoglucosan (neutron data). The ellipsoids are drawn at the 50% probability level. [Symmetry codes: (i) + x, − y, 1 − z; (ii) + x, − y, −z; (iii) −x, + y, − z; (iv) −1 + x, y, z; (v) − + x, − y, 1 − z; (vi) − − x, −y, + z; (vii) − x, −y, + z; (viii) − + x, − y, −z.] The sequence of fundamental O—H⋯O interactions [O3(H)ii⋯O2(H)⋯O4(H)i⋯O1viii] is portrayed on the right-hand side. Labels of some atoms not involved in hydrogen bonding have been omitted for the sake of clarity. |
