First and second group metal carbonyls possible?
I've recently read somewhere that most metals form metal carbonyls. Immediately, I started searching for information
about alkaline/alkaline earth carbonyls, but to no avail. Do they
actually form? I'll be very grateful for any references

Potassium carbonyl is supposedly an explosive compound. I've seen it tossed around as a general hazard while making potassium via reduction methods
involving carbon.

I found this.

Hopefully, this will help. ![:)](./images/smilies/smile.gif)

I'm pretty sure that instead of "metal carbonyl", ions like croconate (CO)5(2-) and squarate (CO)4(2-) are formed when CO reacts with strongly
reducing metals. For example, potassium reacts with carbon monoxide to form hexapotassium benzenehexolate:

This. You can't form a carbonyl with a group IA or IIA metal because they have no available d orbitals. The bond between a metal and carbon monoxide
results from overlap between the molecular orbitals on CO and the d orbitals of the metal. That's why main group metals like tin and lead don't form
carbonyl complexes, either.
Please remember: "Filtrate" is not a verb.
