In this work, the masses of the ground states coupling to molecular or tetraquark currents with JPC = 0++, 1++, 2++ are studied to investigate the structure of X(4140) exotic meson observed at J/ψϕ invariant mass spectrum. We found that all currents predict ground states with masses of the same magnitude, which might be inter-pereted as the existance of at least three exotic structures with degenerate mass.
