1,4,7-Trimethyl-1,4,7-triazacyclononane is the heterocyclic compound with the formula (CH2CH2NCH3)3. This colorless liquid is the N-methylated derivative of triazacyclononane (TACN), a face-capping ligand that is popular in coordination chemistry. Unlike TACN, Me3TACN does not form 2:1 complexes owing to its greater bulk.[1]
Several related tridentate ligands have been prepared with diverse substituents on nitrogen.[2]
