Pincer-Supported Carbonyl Complexes of Cobalt(I)

A pair of POCOP-supported mono- and dicarbonyl complexes of Co have been prepared and crystallographically characterized. The reactivity of (tBuPOCOP)­Co­(CO) with H2, acids, and carbon monoxide has been compared to that of the previously reported Rh and Ir counterparts. Co is found to share reactivity traits with both Rh and Ir.
