Dalton communication. Synthesis and crystal structure of {[Au2(dien)2]2+}n(dien = diethylenetriamine), an infinite linear polymer based on weak gold–gold contacts

Abstract

The complex {[Au₂(dien)₂][BF₄]₂}_n(dien = diethylenetriamine) has been synthesised and characterised by IR and NMR spectroscopy; the crystal structure of its ethanol solvate revealed that the molecular cation has a 16-atom ring structure and an interesting polymeric structure based on weak gold–gold contacts which extends infinitely in the (111) direction.
