Figure 1
The structure of (I), showing the atom-labelling scheme and the two-point anion bridge. The dashed line denotes a hydrogen bond and the dotted line denotes the close contact. Displacement ellipsoids are drawn at the 30% probability level. Occupancy factors for Br/Cl: 0.683 (3):0.317 (3) for the Br1 site, 0.169 (3):0.831 (3) for the Cl2 site, 0.834 (3):0.166 (3) for the Br3 site, 0.810 (4):0.190 (4) for the Br4 site, 0.571 (3):0.429 (3) for the Br5 site, 0.635 (3):0.365 (3) for the Br6 site, 0.066 (3):0.934 (3) for the Cl7 site and 0.641 (3):0.359 (3) for the Br8 site. |
