AX6, AX5E and AX4E2 Configurations
Molecules in this category may have five, six or seven atoms.  The configuration is specified as AX6 for the case with seven total atoms, AX5E for the case with six atoms and AX4E2 for the case with five atoms.  Remember the "E" represents electron groups that are not involved in bonding, the "X" atoms around the central atom and the "A" is the central atom.  Molecules of the type AX6 are octahedral, molecules of the type AX5E  are square-pyramidal and molecules of the type AX4E2 are square-planar.

Molecular Viewer Instructions
Brief Instructions for Molecular Viewer
(The Open Source Applet JSmol/Jmol)

When you select a molecule you will see a rotating image of the molecule displayed above using the Jmol/JSmol applet.
Rotate the molecule Hold down the mouse button and drag the cursor over the image.
Zoom the view Hold down the shift key and the mouse button while dragging up or down over the image
Start/stop automatic spin Right-click over the image and select "on" or "off" from the "Spin" submenu. On a single button mouse try holding the <option>, <ctrl> or <cmd> keys down while holding the mouse button.

Additional instructions for the viewer.

If your browser is not Javascript capable you can still download the molecule files readable by Jmol by clicking on the link and then use Jmol to view the files.  See the tutorial introduction for more information.
