I’d love to see what the molecular orbitals look like. It’s not every day that you see carbon forming six “bonds”.

The nearest that I can picture is three banana bonds with three centres and two electrons for each boron; one Cl-B-B, two B-B-B. (Boron loves this sort of gimmick bond.) Something similar should apply to the carbon, one H-C-B and two B-C-B.

Except that the atoms keep shuffling their bananas back and forth, so it's more like resonant bananas. What a mess.
