Abstract

A series of six silver(i) trifluoroacetate complexes containing new ligands each composed of a quinolinyl or pyridyl nucleus bearing one or two terminal ethynyl substituent(s) has been synthesised. Single-crystal X-ray analysis of the complexes established the coordination preferences of the ethynide substituent(s) at variable positions with respect to the nitrogen donor atom, which serve as dominant factors in directing the construction of multi-dimensional organosilver(i) networks, which are consolidated by weak intermolecular interactions in supramolecular assembly.

Zukerman-Schpector) 2012 Ch. 13, pp. 323–366, (Wiley: Chichester). The term “silver–ethynide” is preferred to “silver–ethynyl” because the silver–carbon bonding interaction is considered to be mainly ionic with minor covalent σ and π components; the negative charge residing mainly on the terminal C atom draws neighbouring AgI atoms close to one another to facilitate the onset of argentophilic Ag···Ag interactions.
