Synthesis and structure of (PPh4)2Na[Cr3(SCH2CH2O)6] containing a linear chromium(III) trimer with terminal thiolate and bridging alkoxide linkages
Abstract
(PPh4)2Na[Cr3(SCH2CH2O)6]·2EtOH has been obtained from the reaction of CrCl3(THF)3(THF = tetrahydrofuran) with HSCH2CH2OH–2NaOEt in EtOH; the anion is the first example of a linear chromium(III) trimer and contains antiferromagnetically-coupled metal centres with an S= 3/2 ground state.
