Ovoid fullerenes with pentagonal fusion

Fullerenes that contain three-fused carbon pentagons break the rules for those molecules but with a little chlorination can be synthesized nevertheless, thanks to efforts by chemists in China. The synthesis of these unusual molecules could lead to new insights into fullerene chemistry as well as offering new opportunities for synthesizing novel materials. The team at Xiamen University suggest their work could lead to a whole range of rule-breaking fullerenes.
