Combining fac-Re(CO)3Cl with components of the ligand redox system bmtz/bmtz·-/H2bmtz/H2bmtz.bul.- (bmtz = 3,6-bis(2-pyrimidyl)-1,2,4,5-tetrazine) gave (H2bmtz)Re(CO)3Cl, (m-H2bmtz)Re(CO)3Cl2 and (m-bmtz)Re(CO)3Cl2. 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. Reactivity is obsd. in terms of oxidative proton and reductive chloride dissocn. on SciFinder(R)
