A variant of a bridging carbonyl is the "semi-bridging" carbonyl in which the M-CO-M bond is asymmetric rather than symmetric. Check this image for semi bridging carbonyl 👇

option D Bonding modes of CO CO typically bonds in an end-on fashion through carbon as shown above. However, bridging carbonyls are not uncommon and often undergo exchange with te...
