name of molecule structure

What is the structure of SCl4 called? Just means the structure has five element, but it has another one pair on its center atom.

SCl4 is called sulfur tetrachloride, it has 5 areas of electron density so it is in the group of trigonal bipyramidal and it has the shape of seesaw. Due to the 1 lone pair on the sulfur and 4 bonds.

When drawn out, sulfur tetrachloride has 4 single bonds of S-Cl coming off of sulfur. After accounting for the octet rule, you get 32 electrons, but you need 34. So, a lone pair is added to the sulfur atom. Thus, the molecule has 5 regions of electron density (4 single bonds and 1 lone pair). This puts the molecule within the trigonal bipyramidal group. But, the molecular shape of SCl4 is actually a seesaw because the one lone pair distorts the bond angles which changes the overall shape.

This shape is known as a seesaw shape, where the it can be written as AX4E

First, we count the electron densities which is 5 (4 bonding pairs and 1 lone pair). It has the electron geometry of trigonal bipyramidal. However, instead having this structure, having 4 bonding pairs and 1 lone pair is called seesaw.
