are antiferromagnetic in nature. Complexes with the Fe4O2 core (1 and 2) and the Mn4O2 core (3 and 4) possess an St = 0 and St = 3 ground state, respectively, regardless of the nature of the bridging carboxylate ligand. In contrast, changing the bridging carboxylates in the [Fe2Mn2O2] core from acetate (5) to diphenylglycolate (6), triphenyl acetate (7), benzoate (8), chloroacetate (9) and propionate
