Abstract
In this article, we take the point of view that the nonet mesons below are diquark-antidiquark states , and devote to determine their masses in the framework of the QCD sum rules approach with the interpolating currents constructed from scalar-scalar type and pseudoscalar-pseudoscalar type diquark pairs respectively. The numerical results indicate that the nonet mesons may have two possible diquark-antidiquark substructures.
