Abstract

This overview describes the different roles that borane and carbaborane clusters play in the assembly of coordination polymers and networks. The review uses data in the Cambridge Structural Database as a starting point to exempify the variety of 1D, 2D, and 3D-architectures that have been described featuring borane and carbaborane cages. The roles of these clusters range from 'space fillers' to rigid-rods (linkers) to connecting nodes. Even as 'space fillers', some clusters may play a critical role, for example, the templating effects of the spatially demanding [Co(C 2 B 9 H 11 ) 2 ] − cage. Arguably, some of the most important roles of carbaborane clusters are as scaffolds for the design of di-, tri-, and tetratopic multifunctional carboxylate linkers. These mimic arene-centred organic linkers which are well-established as linkers or connecting nodes 2D- and 3D-networks. The different spatial demands of the cluster- versus arene-cores may lead to significant differences in the resulting architectures. Finally, the role of three-centre two-electron B-H-M interactions in the assembly of polymeric structures in the solid state is illustrated, mostly with M = alkali metal or silver(I)
