Concomitant, genuine 1D supramolecular isomers of an Ag(I) complex with 1,3-bis(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene and BF4- as counterion

摘要

Two 1D concomitant, conformational supramolecular isomers of an Ag(I) complex with the ligand 1,3-bis(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (bitmb) and BF4- as counterion of general formula {[Ag(bitmb)(2)](BF4)(n)} were isolated. The crystal structures nicely point out the ligand's flexibility, showing syn-conformation in 1a and anti in 1b, as well as different contributions of non-covalent interactions, participating in the formation of the corresponding supramolecular assemblies. Furthermore, the geometry around the silver ions is also influenced by the conformational changes. (C) 2015 Elsevier B.V. All rights reserved.
