As a consequence of their high instability, main-group carbonyl complexes are rare — only a few have been detected, typically in low-temperature matrices. Now, two silicon–carbonyl complexes have been isolated using innovative substituent patterns at the Si centre; their reactivity resembles that of their transition-metal counterparts.
