The new diethanethiol-dipyrrolidinyl PNP-lar iat ether, L2, was syn the sized. Spectral properties of the tetrapyrrolidinyl PNP-lar iat ether L1 as well as L2 and their complexes with silver cat ion were investigated. The formation constants of the complexes with Ag+ in methanol solutions were determined. The 1H NMR and potentiometric measurements in dicate that in both cases complexation of Ag+ ions pro ceeds with participation of endocyclic nitrogen atom of cyclophosphazene ring and of polyether oxygen donors. In the case of L2 there is no evidence for stabilization of the ob tained complex by ethanethiol sub units attached to the exocyclic P atom. There is also no evidence for additional stabilization by cyclophosphazene ring or any of the pyrrolidinyl groups.
