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

• Concomitant, genuine, conformational supramolecular isomers have been isolated.
• The conformational change of the ligands does not cause a change in the topology of the network.
• The distribution of the non-covalent interactions differs significantly in both isomers.

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.
