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 ...
Osaka, Japan – The arrangement of small molecules – known as ligands – around transition metal atoms affects how the metal atoms behave. This is important because transition metals are used as ...
The 'classical' shape of four-coordinate nitrogen, carbon and boron compounds is tetrahedral, as predicted by the valence-shell electron-pair repulsion theory that all chemists learn at an early stage ...
