It will probably dissociate into two ${O}_{2}$ molecules. In fact there have been many failed attempts to make ${O}_{4}$.

#### Explanation:

${O}_{4}$ is called tetraoxygen, which was first predicted back in 1924 by Gilbert Lewis. There are no forms of stable ${O}_{4}$ molecules except possibly under extremely high pressure.

The basic problem is that with 6 electrons in the valence shell of each O atom, it's difficult to get enough overlap between singly-occupied p orbitals to form the O-O bonds without the energy being overcome by repulsive interactions of the non-bonding electrons.
