Figure 1
The structure of (I[link]), showing the role of the [BeF4]2− anion in hydrogen-bond formation (dashed lines). Displacement ellipsoids are drawn at the 50% probability level. H atoms connected to the C atoms of symmetry-related cations have been omitted for clarity, while the remaining H atoms are shown as open circles. The labelling scheme encompasses all non-H atoms of the asymmetric unit and selected other atoms [symmetry codes: (i) [{3 \over 2}] − x, y − [{1 \over 2}], [{1 \over 2}] − z; (ii) [{1 \over 2}] + x, [{1 \over 2}] − y, z − [{1 \over 2}]; (iii) [{1 \over 2}] − x, y − [{1 \over 2}], [{1 \over 2}] − z; (iv) [{1 \over 2}] + x, [{1 \over 2}] − y, [{1 \over 2}] + z; (v) 1 + x, y, z].
