A homonuclear diatomic molecule C2 can be observed........

Explanation:

It is not something you could put in a bottle, but the homonuclear diatomic, C2, has been observed spectroscopically. I think this molecule has a bond order of 2, i.e. :C=C:, so it is relatively stable. It would need quite elevated temperatures to enable its observation.
