The properties of the new Mn(II)–Co(II)–Mn(II)-type hetero-trinuclear oxime metal complexes with N4 and N4O2 ligands

The synthesis, characterization, and electrochemistry of molecular cobaloxime/organocobaloxime: catalysts for cycloaddition of carbon dioxide and epoxides

“…In 3-10, perchlorate show strong antisymmetric stretching bands at 1090 cm −1 and sharp antisymmetric stretching bands at 625-623 cm −1 , an indication of uncoordinated perchlorate anions [21,22]. These values are in agreement with those for cobaloxime (1), organocobaloxime (2), and the trinuclear cobaloxime and organocobaloxime (3-10) complexes.…”
