Abstract
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.
Keywords: Copper(II) complexes, dicyanoargentates(I), cyano-bridged complexes, X-ray structure analysis
