Thiolatokomplexe des einwertigen Golds. Synthese und Struktur von [(2,4,6‐<i>i</i>Pr₃C₆H₂S)Au]₆ und (NH₄)[(2,4,6‐<i>i</i>Pr₃C₆H₂S)₂Au]

Abstract

Thiolato Complexes of Monovalent Gold. Synthesis and Structure of [(2,4,6‐ i Pr 3 C 6 H 2 S)Au] 6 and (NH 4 )[(2,4,6‐ i Pr 3 C 6 H 2 S) 2 Au] Reaction of Au(CO)Cl with 2,4,6‐tri(isopropyl)thiophenol affords hexameric gold(I) thiolate [(2,4,6‐ i Pr 3 C 6 H 2 S)Au] 6 ( 1 ). According to an X‐ray analysis 1 forms a centrosymmetrical twelve‐membered Au – S ring in the chair conformation with the linearly coordinated Au atoms at the mid‐edges and the S atoms at the corners of the heterocycle. When the reaction of 2,4,6‐tri(isopropyl)thiophenol is carried out with AuI in liquid ammonia the thiolato complex [(2,4,6‐ i Pr 3 C 6 H 2 S) 2 Au] – ‐NH + 4 ( 2 ) is obtained. It crystallizes as NH 4 · 2 · 3 NH 3 . The gold atom in 2 is linearly coordinated by two thiolato S atoms. The ammonium cation forms hydrogen bonds with three NH 3 solvate molecules.
