Cover illustration: In C6H26B20Se3, two closo-C2B10 icosahedra are linked by a chain of three selenium atoms: the Se-Se bond lengths suggest that they can be regarded as single bonds. The C-Se-Se-Se torsion angles indicate a strongly twisted conformation for the linking triselenide grouping. See Ilie, Soran, Laguna & Silvestru [Acta Cryst. (2011). E67, o1908].
