Abstract

In the structural motifs of two isomorphous triclinic salts, (C5H6Br2N3)2[MBr4] (M = Cd(II) and Mn(II)), each [MBr4]2- anion interacts with eight surrounding 2,6-diamino-3,5-dibromopyridinium cations through intermolecular C/N-H...Br and Br...Br interactions, leading to a three-dimensional framework structure. The cations show a minor degree of pi-pi stacking, adding extra stability to the three-dimensional architecture.
