The first crystal structure involving Schiff base containing 4-substituted 1,2,4-triazolium cation is reported. The neutral (4-chloro-benzylidene)-[1,2,4] triazol-4-yl-amine (T) and protonated (HT+) molecules are connected by the strong [N-H...N]+ hydrogen bond forming the discrete dimers. The pair of the dimers and two BF4 _ ions are linked via the weak C-H...F interactions and create tetrameric units. BF4 _ ions mediate between succeeding tetramers and as a result double ribbons along [110] are formed. No intermolecular, directional interactions between neighbour ribbons in the crystal were found.
