The title complex, [Ag2((Me-pk)2en)2](ClO4)2 {(Me-pk)2en = N,N′-bis[(pyridine-2-yl)acetylidene]ethane-1,2-diamine}, has been synthesized and structurally characterized by single-crystal X-ray diffraction. The (Me-pk)2en acts as a tetradentate ligand coordinating via four N atoms to two silver(I) centers. The complex forms double-helical structure with the two silver ions in distorted square pyramidal.
