VSEPR Theory: A closer look at trifluorothionitrile, NSF3.

Abstract

The post on applying VSEPR ("valence shell electron pair repulsion") theory to the geometry of ClF <sub> 3 </sub> has proved perennially popular. So here is a follow-up on another little molecue, F <sub> 3 </sub> SN. As the name implies, it is often represented with an S≡N bond. Here I take a look at the conventional analysis. This is as follows: Six valence electrons on the central S atom.
