Abstract:
The title compound is not a hexaboride, as was believed for many years. It is therefore not surprising that its structure also contains a novelty: for the first time a pentagonal B7 bipyramid (shown on the right) has been identified as part of the framework of boron atoms in a solid-state compound.
