Abstract

The templating effect of the tetrafluoroborate ion leads to assembly of four Co^II ions and six bridging ligands around this anion to give a tetrahedral complex with a bridging ligand along each edge and the anion trapped in the central cavity (shown below). Surprisingly under identical conditions but with Ni^II a simpler dinuclear complex forms.
