Olympic is a hydrocarbon . The molecule consists of five rings, four of which are benzene rings, linked together similar to the shape of the Olympic rings.
The molecule was proposed in March 2010 by Graham Richards of the University of Oxford and Antony Williams in celebration of the 2012 London Olympics . It was first synthesized by Anish Mistry and David Fox from the University of Warwick in the UK. The relative energies of olympics and its isomers were initially predicted from quantum electronic structure calculations by Andrew Valentine and David Mazziotti of the University of Chicago .

Images of the molecule were made using scanning tunneling microscopy . More detailed images were made by IBM researchers in Zurich with the help of non-contact atomic force microscopy in 2012.
