Figure 2
Two parallel polymeric chains of one layer in β-HBO2 projected on (102). The two H2O molecules seen between the two chains belong to chains in adjacent layers above and below. B atoms are shown as black spheres, O atoms as hatched spheres and H atoms as white spheres of arbitrary radii. Major (minor) components of hydrogen bonds are represented as thin (dashed) lines (DIAMOND; Brandenburg & Berndt, 1999). |
