The tetrahedral geometry of four-coordinate carbon atoms is a steadfast property of organic compounds. Nevertheless, chemists are still attracted to the possibility of twisting or squashing a ...

Meet Bille, the name given to the world's first monostable tetrahedron—a four-faced object that will always land on the same side, no matter its starting position. This feat of geometry and ...

To celebrate C&EN’s 90th anniversary, one Editor’s Page each month examines materials from C&EN Archives. Featured articles are freely downloadable for one month. The tetrahedral geometry of, and the ...

Planar tetracoordinate carbon species subvert the long‐standing paradigm of tetrahedral carbon geometry, demonstrating that a carbon atom can be stabilised in a planar configuration with four ...
