Template synthesis, characterization and reactivities of anionic transition metal complexes with tetraazaprotonated 11,13-dimethyl-1,4,7,10-tetraazacyclotrideca-4,6,10,13-tetraene-5,6-diol as cation has been achieved. By magnetic and spectral studies, hexachlorometallate(II) anionic complexes have been found to be octahedral. It is envisioned that the cationic macrocycle may be associating with both the complex and chloride anions through hydrogen bonding thereby rendering the molecule as a whole neutral. Deprotonation, protonation analysis and chemosensor behaviour have been showed by pH variation studies and relevant anionic additions, respectively. All of these data supports the newly synthesized anionic complexes in a strange manner.
