significant role. Three dinuclear Hg(I) complexes were isolated which contain an Hg2}2+ metal–metal bonded core bound to a single bis-bidentate ligand which can span both metalions. Also characterised were a series of Hg(II) complexes comprising a simple mononuclear four-coordinate Hg(II) complex, a tetrahedral HgII4 cage which incorporates a counter-ion in its central cavity, a trinuclear double helicate
