A novel alkoxide bridging motif between boron trifluoride and copper(ii) in a crown thioether complex
Abstract
Reaction of 6-hydroxy-1,4,8,11-tetrathiacyclotetradecane (LH) with Cu(BF4)2 in THF yields [Cu(LH)](BF4)2; crystallisation of the complex from MeNO2/Et2O gives brown crystals of [Cu(LBF3)](BF4), the first example of alkoxide bridging between BF3 and a metal centre.
