Figure 1
The structure of (I), showing the atom-numbering scheme, with displacement ellipsoids drawn at the 50% probability level. The molecule lies on a crystallographic inversion center with the symmetry-equivalent portion generated by the operation (−x + 1, −y + 1, −z + 1). The metal atom is half-occupancy because it is disordered over the center, and only one position is displayed. The above description applies equally to (II). |
