The image on the left is a helical ribbon and a nanotube of titanium dioxide (TiO₂). These structures were produced by a research group in Japan (ref.: Chem. Mater. 2002, 14, 1445-1447).

The image on the right is a three-alpha-helical bundle of peptides that have bound two Cd(II) ions (blue). This material was produced by Manolis Matzapetakis in Dr. Pecoraro's research lab.

Middle image represents a crystal stucture of a catechol Ruthenium Carbide complex. Ruthenium terminal (one coordinate) carbide complexes are very rare.The majority of metal terminal carbides known have been synthesized in the Johnson group including the carbide shown above synthesized by Michael Stewart.

12-MC-4

The above structure is a 12-MC-4 Metallacrown with 4 ring Cu(II) centers and 1 central Cu(II) center. This stucture is the inorganic analogue to 12-Crown-4. This molecule was also produced in Dr. Pecoraro's lab. Color Scheme: Nitrogen=Blue, Carbon=Gray, Oxygen=Red, Copper=Dark Red. The above is a Chime file. Click on the image to open a better view of the molecule. If you click and hold your left mouse button on the image, you can rotate the molecule by dragging your mouse. Also, if you right click on the image, a menu with different display options will appear.
