Figure 1
(a) A view of the penta­nuclear [Cu5Br7]2− anion, (b) a polyhedral view of the same unit (generic atom labels without symmetry codes have been used) and (c) a displacement ellipsoid plot (50% probability level) of the emim cation showing the atomic numbering scheme. The dotted line in (a) indicates the position of the mirror plane and connects atoms in special positions. [Symmetry codes: (i) x, −y + [{1\over 2}], z; (ii) x + [{1\over 2}], −y + [{1\over 2}], −z + [{1\over 2}]; (iii) x + [{1\over 2}], y, −z + [{1\over 2}].]
