The weak hydrogen-bonding interactions (light-grey dashed lines) and strong interactions (black dashed lines) which stabilize the overall structure in (II). Atoms marked with the suffixes a, b, c, d, e and f are at the symmetry positions (1 − x, 1 − y, 1 − z), (1 − x, − + y, − z), (1 − x, − + y, − z), (1 − x, + y, − z), (x, − y, + z) and (x, − y, − + z), respectively. |
