A new type of supramolecular entanglement in the silver(I) coordination polymer [Ag₂(bpethy)₅](BF₄)₂ [bpethy = 1,2-bis(4-pyridyl)ethyne]

Abstract

The polymeric compound [Ag₂(bpethy)₅](BF₄)₂, obtained from AgBF₄ and 1,2-bis(4-pyridyl)ethyne (bpethy) in molar ratio 1:3, contains infinite molecular ladder motifs with monodentate ligands as sidearms on both sides, that are threaded through the squares of adjacent polymeric units in a mutual relationship, to give infinite ‘polythreaded’ bidimensional layers.
