Abstract: The species originally reported as [Co(bipy) <subscript>2</subscript> O <subscript>2</subscript> BOH]·[B <subscript>5</subscript> O <subscript>6</subscript> (OH) <subscript>4</subscript> ]·H <subscript>3</subscript> BO <subscript>3</subscript> ·H <subscript>3</subscript> O·H <subscript>2</subscript> O, a Co(II) complex containing a chelated O <subscript>2</subscript> BOH <superscript>2-</superscript> ligand, is shown to be [Co(bipy) <subscript>2</subscript> O <subscript>2</subscript> CO]·[B <subscript>5</subscript> O <subscript>6</subscript> (OH) <subscript>4</subscript> ]·H <subscript>3</subscript> BO <subscript>3</subscript> ·2H <subscript>2</subscript> O, a Co(III) complex containing a chelated O <subscript>2</subscript> CO <superscript>2-</superscript> ligand. This was confirmed by <superscript>1</superscript> H and <superscript>13</superscript> C NMR, MS, IR, and an X-ray crystal structure.
