The utility of N-methylimidazole and acetonitrile as solvents for the direct reaction of europium with alcohols including the first example of acetonitrile as a µ-η1:η1-bridging ligand

Abstract

N-Methylimidazole and acetonitrile are suitable solvents for the direct reactions of europium metal with 2,6-Me₂C₆H₃OH and 2,6-Prⁱ₂C₆H₃OH, which lead to crystallographically characterizable (N-methylimidazole)₃Eu(µ-OC₆H₃Me₂-2,6)₃Eu(N-methylimidazole)₂(OC₆H₃Me₂-2,6) 1 and [(MeCN)₂(2,6-Prⁱ₂C₆H₃O)Eu]₂(µ-OC₆H₃Me₂-2,6)₂(µ-NCMe) 2, a complex which contains a µ-η¹-acetonitrile ligand.
