Figure 2
The coordination polyhedron in compound (II), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level and the atoms marked `a', `c' and `e' are at the symmetry positions (1 − x, − + y, − z), (1 − x, 1 − y, 1 − z) and (x, 1.5 − y, + z), respectively. |
