The first chelating olefin: Solid-state structure of bis-(η1-4-phenyl-η2-1-butene)silver (I) tetrafluoroborate

A complex of 4-phenyl-1-butene with silver ion has been prepared by mixing silver (I) tetrafluoroborate with the neat ligand at room temperature. Purification by crystallization produces a stable complex characterized by solid-state structure. The bis-(η1-4-phenyl-η2-1-butene)silver (I) tetrafluoroborate complex contains a pair of olefin ligands that chelate a single silver atom via both olefin and aromatic Ag–C bonds. This is the first chelated organometallic silver complex reported in the literature assembled with only Ag–C bonds.
