The crystal packing of (I) (top left), viewed along the a-axis direction, the crystal packing of (II) (top right), viewed along the a-axis direction and the crystal packing of (III) (bottom), viewed along the b-axis direction. The hydrogen bonds (Tables 1–3) are shown as dashed lines. Displacement ellipsoids are drawn at the 50% probability level. Hydrogen atoms not involved in hydrogen bonds are omitted for clarity. Only one component of disorders are shown. |
