At room temperature, this monocarbonyl can associate with excess I to give (C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>Co<sub>2</sub>(CO)<sub>3</sub>, or dimerize to (C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>Co<sub>2</sub>(CO)<sub>2</sub>. The latter is stable as a solid, but in solution it is slowly converted to the insoluble trimer (C<sub>5</sub>H<sub>5</sub>)<sub>3</sub>Co<sub>3</sub>(CO)<sub>3</sub>. (C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>Co<sub>2</sub>(CO)<sub>2</sub> is symmetrically cleaved by phosphines to (C<sub>5</sub>H<sub>5</sub>)Co(CO)(PR<sub>3</sub>), while diolefins bring about unsymmetrical cleavage to give (C<sub>5</sub>H<sub>5</sub>)Co(diolefin) and (C<sub>5</sub>H<sub>5</sub>)Co(CO)<sub>2</sub>.
