Titanium falls flat in an eight-membered boron ring

Researchers in China and the US have predicted the first two-dimensional material to contain completely planar octacoordinate transition metal atoms – TiB4. If scientists can make it, the monolayer would contain edge-sharing wheels of eight-membered boron rings with a central titanium atom.
