Observation of ppm*, muonic proton-proton metastable ionic molecules, has been reported in recently published papers. They are produced in interactions of mps2sd atoms with protons. These ionic molecules play an important role in the muon-catalyzed fusion cycle. The structure of ppm* is studied here using the variational method and by a related suitable wave function. Through this approach, the energies and nuclear size in the resonance states for ppm* are calculated. To assess the reliability of the given wave function, the formation rate is also calculated. The obtained results are close to those previously reported and give strong indications that the related wave function is good enough for determining the resonance states of this mentioned ionic molecule.
