Assembly of a novel cyclic dimer encapsulating PF6- into the brick wall network

The cyclic silver (I) dimer [Ag(m-bitmb)](2)(PF6)(2) . 2MeCN of 1,3-bis(imidazolylmethyl)-2,4,6-trimethylbenzene (m-bitmb) was prepared and its structure characterized by X-ray crystallography. An PF6- anion is encapsulated within the macrocyclic cation [Ag(m-bitmb)](2)(2+) with weak Ag . . .F and CH . . .F interactions. Two types of intermolecular pi-pi interactions lead to a brick wall 2 network. (C) 2001 Elsevier Science B.V. All rights reserved.
