A near-planar pentadentate silver(<scp>I</scp>) complex; the crystal and molecular structure of (2,2′ : 6′,2″ : 6″,2‴ : 6‴,2â�—-quinquepyridine)silver(<scp>I</scp>) hexafluorophosphate

Abstract

The complex [AgL1][PF6](L1= 2,2′ :6′,2″ :6″,2‴ : 6‴,2â�—-quinquepyridine) has been prepared and structurally characterised; in contrast to the double helical binuclear complexes formed with first row transition metal ions, the title complex is mononuclear, with a near-planar arrangement of the ligand about the metal, and the cation exhibits weak π-interactions with adjacent cations, but there is no direct Ag–Ag interaction.
