摘要：

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.
