Creating a ChemPen3D Model

Creating a ChemPen3D Molecular Model

Step 1 Add a cobalt atom. Type + twice to change the Co charge to (+2). Now join three five member rings to the cobalt atom as shown.	Step 2 Point to each Co bonded C and type N to change it to NH.
Step 3 Point to each NH and type U to change each to an NH₂.	Step 4 Select File\| 3D Geometry\| Optimize to optimize the geometry of the molecule. On a 75Mhz Pentium© optimization took about 4 seconds.
Step 5 Select Add Hs 3D to protonate the molecule. Protons automatically move to their proper positions. For a true energy minimum the molecule would still be to be geometry optimized.	Step 6 Select File\| 3D Geometry \| 3D Views. Click the bottom right image to change the view to the view shown.
