Abstract
[Re(riboflavin)(CO)(3)Cl] shows intraligand (lambda(max) = 476 and 518 nm) and Re(I) to pi (riboflavin) metal-to-ligand charge transfer, ML CT, (lambda(max) = 556 nm, in CH3CN) absorptions in close proximity. T he MLCT band undergoes a moderate solvent-dependent shift (negative so lvatochromism) indicating a partial charge separation in the excited s tate. The complex is not photoluminescent.
