Other species characterized were (bmtz)Re(CO)3Cl (UV/visible, IR), (H2bmtz)Re(CO)3Cl.bul.- (UV/visible, IR, EPR), (μ-H2bmtz)Re(CO)3Cl2.bul.- (UV/visible, IR, EPR) and (μ-bmtz)Re(CO)3Cl2.bul.- (UV/visible, IR, X band and high-field EPR). The results confirm bmtz as very strong and H2bmtz as moderate p acceptor ligand vs. one or two chelate-bonded low-valent metal centers.
