As i've been reading on Wikipedia, we are artificially able to join an antiproton with a positron to form an antihydrogen.
But if i search for antimolecule, i can't find any results on that, only a definition. Though they say that according to the laws of physics, antimatter follow the same rules (in their own domain).
So my question is, have we been able to form an antimolecule in the sense of a molecule composed by different "antiatoms" - for example a molecule of $H_2O$ (2 hydrogen atoms, 1 Oxygen)? Is there an antimolecule formed by 2 AntiHydrogen and 1 AntiOxygen.
Or for example an antimolecule for $H_2$ (without having to build an AntiOxygen)?
The main reason of this question is: is it proven that the forces that bind particles together and atoms together to form a molecule, apply similarly on antiparticles?
