Syntheses and Photochemical Properties of Trimanganese Complexes Containing Naphtyl Moieties

Two trinuclear manganese complexes, [Mn3(μ3–O)(μ–O2CCH2-1-naph)6(py)3] (1) and [Mn3(μ3–O)(μ–O2CCH2 2-naph)6(py)3] (2) (1 or 2-naph-CH2CO2H = 1 or 2-naphtylacetic acid, py = pyridine), were synthesized and characterized by elemental analysis, EXAFS analysis, and X-ray crystallography. Their electrochemical and photochemical behaviors were investigated by cyclic voltammetry (CV), electron absorption spectroscopy, and emission spectroscopy.
