The novel compound, {[Cu(medpt)][Ag(CN)2]2}n (medpt = N,N-bis-(3-aminopropyl)methylamine), was isolated from a reaction mixture containing Cu(ClO4)2 · 6H2O, medpt and K[Ag(CN)2]. The new complex was characterized by IR spectroscopy, magnetochemical studies and by X-ray single crystal diffraction. The structure contains [Cu(medpt)]2+ units being bridged by [Ag(CN)2] units resulting in chains of the composition [–μ–CN–Cu(medpt)–μ–NC–Ag–]n, and dicyanoargentate anions. Ag...Ag interactions link free [Ag(CN)2] anions to the chain. The copper(II) atom is five coordinated to two cyanide-nitrogen and three medpt-nitrogen atoms in a distorted square-pyramidal arrangement.
