The Silver(I) – Complexes of Cyclic Polyamines with Pendant-arm Modification

The complex formation for two different groups of cyclic polyamines with four or six nitrogen atoms and with pendant-arm modification and silver(I) ions in propylene carbonate has been studied by electron spray ionization mass spectrometry (ESI MS), potentiometric and Austin Model 1 (AM1d) semiempirical methods. The stability constants of complexes are determined by potentiometric method. The structure of those complexes are visualised by AM1d semiempirical calculations.
