Figure 1
The molecular structure of (I ), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level. One of the two possible conformations of the disordered ethylenediamine moiety has been omitted for clarity. Atoms marked with a prime (′), asterisk (*), double prime (′′) or hash (#) are at the symmetry-related positions (x, ½ − y, ½ − z), (1 − x, ½ − y, z), (−x, y, ½ − z) and (½ − x, 1 − y, z), respectively. |
