A large variety of N-substituted 1,3,5-triazacyclohexanes (R3TAC) can be easily prepared from formaldehyde and primary amines. We are investigating the general coordination chemistry with transition metal ranging from the lanthanides to zinc. We are examining the complexes mainly by X-ray crystallography, UV/visible, IR, Raman, and NMR spectroscopy.
R3TAC occupies three coordination sites of the metal with unusually small N-metal-N angles of 60-65°. This leads to low steric demand of the ligand and allows the preparation of unusual complexes and increased catalytic activity in general.
