Synthese und Strukturen der selenolatoverbrückten Quecksilbercluster [Hg6(SePh)12(PtBu3)2] und (HPtBu3)2[Hg6(SePh)14]

Synthesis and Structures of the Selenolato-Bridged Mercury Clusters Hg₆(SePh)₁₂(P t Bu₃)₂] and (HP t Bu₃)₂Hg₆(SePh)₁₄] The reaction of HgCl₂ with PtBu₃ and PhSeSiMe₃ yields Hg₆(SePh)₁₂(PtBu₃)₂] ( 1 ) and (HPtBu₃)₂Hg₆(SePh)₁₄] ( 2 ). X-ray structural analysis of the compounds shows them to have similar Hg–Se cages with distorted tetrahedral coordination around mercury. The cages are built up from edge- and vertex-sharing distorted tetrahedra.
