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]

Generic octahedral metal complex of Me₃TACN.
