On the transport and selective complexation of silver(I) by mixed thioether–oxa crowns. The single crystal X-ray structures of [Agn([15]aneS2O3)n](PF6)n and [Ag2([15]aneS2O3)3](PF6)2([15]aneS2O3= 1,4,7-trioxa-10,13-dithiacyclopentadecane)

Abstract

Reaction of AgNO₃ with [15]aneS₂O₃ followed by addition of NH₄PF₆ affords the complexes [Ag_n([15]aneS₂O₃)_n](PF₆)_n and [Ag₂([15]aneS₂O₃)₃](PF₆)₂; the complex [Ag_n([15]aneS₂O₃)_n]ⁿ⁺ is an S-bridged linear-chain polymer of [Ag([15]aneS₂O₃)]⁺ units with formal S₂O₃S_bridge coordination at Ag^I, while the binuclear species [Ag₂([15]aneS₂O₃)₃]²⁺ shows distorted trigonal planar S₃ coordination at Ag^I with long-range interactions to three O-donors at each Ag^I.
