Metathetical reactions of alkali-metal derivatives of the dianion [ t BuN(Se)P(μ-N t Bu) 2 P(Se)N t Bu] 2− ( 2Se 2− ) with Ag(NHC)Cl, Ag[BF 4 ], AuCl(THT) and HgCl 2 , as well as the reaction of 2S 2− with AuCl(THT) were investigated. The observed products all incorporate the monoprotonated ligands 2Se H − or 2S H − in a variety of structural arrangements around the metal centres, including tetrameric and trimeric macrocycles [Ag and Au (E = Se)], a ladder (Au, E = S) and a spirocycle (Hg); the ladder contains both the dianion 2S 2− and the monoanion 2S H − as ligands linking three Au 2 units. All complexes have been characterised in the solid state by single crystal X-ray analyses and in solution by multinuclear ( 1 H, 31 P and 77 Se) NMR spectra. Reactions of the dianions [ t BuN(E)P(μ-N t Bu)] 2 2− (E = Se,S) with M( i ) reagents (M = Ag, Au) or HgCl 2 produce complexes of [ t Bu(H)N(E)P(μ-N t Bu) 2 P(E)N t Bu] − with spirocyclic, macrocyclic or ladder structures.
