Abstract

The coordination of silver(I) acetate with 2,2′ : 6′,2″-terpyridine (tpy) and 6,6″-diphenyl-2,2′ : 6′,2″-terpyridine (dptpy) has been investigated. In contrast to the behaviour with copper(I), no dinuclear double-helical species have been unambiguously isolated although there is evidence that double-helical [Ag²L²]²⁺ complexes exist in weakly-coordinating solvents. In the case of 2,2′ : 6′,2″-terpyridine, a species containing a square-planar [Ag(tpy) (MeCN)]⁺ caton has been isolated and structurally characterised whilst with 6,6″-diphenyl-2,2′ : 6′,2″-terpyridine a related but very distorted [Ag(dptpy)(MeCN)]⁺ species has been structurally characterised.
