In this article, we study the pseudoscalar bound state η c ′f 0(980) (irrespective of the hadro-charmonium and the molecular state) with the QCD sum rules. Considering the SU(3) symmetry of the light flavor quarks and the heavy quark symmetry, we also study the bound states η c ′σ(400−1200), η b '''f 0(980) and η b '''σ(400−1200), and make reasonable predictions for their masses.
