title: Spacer flexibility in bis(pyridyl) ligands: chelating organosilicon pyridylethynyl ligands.
abstract: Two new bis(pyridylethynyl) ligands with organosilicon spacers have been synthesized. The ligands react readily with silver(I) to form crystalline complexes, both of which are revealed to be triflate-bridged dimers by X-ray crystallographic analysis. The complex with the flexible siloxane-based ligand possesses considerably less bond angle distortion.
