Structures of possible transient geometries of [Fe(III)(C2O4)3]3− after 268 nm photoexcitation. Complex 1 represents an unstable geometry of [Fe(III)(C2O4)3]3− with an elongated C-C distance of the oxalate ligand, while complexes 2A and 2B are the isomerized forms. [(CO2•)Fe(II)(C2O4)2]3− is created when complex 1 loses a neutral CO2 molecule from the oxalate ligand. Further details are contained in the text.
