ON THE ROAD TO CARBENE AND CARBYNE COMPLEXES
... carbene ligand is shifted drastically towards lower wave numbers, namely 1953 c m-1 ( Al) (17); that is, the carbene ligand has a much greater (σ donor/π acceptor ratio than CO. In other words the carbene ligand is on the whole positively polarised, and the Cr (CO)5 part is negatively polarised. The ...
