carboxylates. The resulting carboxylato complexes, isolated as ClO4− or BPh4− salts, have been fully characterized by elemental analyses, IR, UV/vis spectroscopy, and X-ray crystallography. The possibility of accessing the [NiII2L(μ-O2CR)]+ complexes by carboxylate exchangereactions has also been examined. The main findings are as follows: (i) Substitution reactions between 1 and NaO2CR are not affected
