Figure 4
The structure of (III), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. Note the combination of the pyridazine and double iodide bridges between the CdII ions. [Symmetry codes: (i) x, −y + , z − ; (ii) x, −y + , z + ; (iii) −x + 1, −y, −z + 1.] |
