Spirocyclic, macrocyclic and ladder complexes of coinage metals and mercury with dichalcogeno P sub(2)N sub(2)-supported anions

Metathetical reactions of alkali-metal derivatives of the dianion [ super(t)BuN(Se)P( mu -N super(t)Bu) sub(2)P(Se)N super(t)Bu] super(2-) (2Se super(2-)) with Ag(NHC)Cl, Ag[BF sub(4)], AuCl(THT) and HgCl sub(2), as well as the reaction of 2S super(2-) with AuCl(THT) were investigated. The observed...

Description
Summary:Metathetical reactions of alkali-metal derivatives of the dianion [ super(t)BuN(Se)P( mu -N super(t)Bu) sub(2)P(Se)N super(t)Bu] super(2-) (2Se super(2-)) with Ag(NHC)Cl, Ag[BF sub(4)], AuCl(THT) and HgCl sub(2), as well as the reaction of 2S super(2-) with AuCl(THT) were investigated. The observed products all incorporate the monoprotonated ligands 2SeH super(-) or 2SH super(-) 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 super(2-) and the monoanion 2SH super(-) as ligands linking three Au sub(2) units. All complexes have been characterised in the solid state by single crystal X-ray analyses and in solution by multinuclear ( super(1)H, super(31)P and super(77)Se) NMR spectra.
