The largest C-C-C angle?

Tuesday, November 1st, 2016

I am now inverting the previous question by asking what is the largest angle subtended at a chain of three connected 4-coordinate carbon atoms? Let’s see if further interesting chemistry can be unearthed.


Deviations from tetrahedral four-coordinate carbon: a statistical exploration.

An article entitled "Four Decades of the Chemistry of Planar Hypercoordinate Compounds"[cite]10.1002/anie.201410407[/cite] was recently reviewed by Steve Bacharach on his blog, where you can also see comments. Given the recent crystallographic themes here, I thought I might try a search of the CSD (Cambridge structure database) to see whether anything interesting might emerge for tetracoordinate carbon.
