Talk:Charge-shift bond

Electron-density contradiction for Mg–Mg example
The major hallmark of a charge-shift bond seems to be an unusually low electron-density between the atoms as compared to a normal covalent bond (in addition to a fairly positive Laplacian). In the experimental evidence section, (Mg-Mg)2+ is used as an example. But the ref cited for it talks about an unusually high electron-density there and region of notably negative Laplacian, even as compared to normal covalent bonds. Is this Mg–Mg example just misplaced, or are other parts of this article mixing charge-shift bonding with some other aspect? We don't (yet) have a non-nuclear attractor article.
