A nonrelativistic model is used to study hidden-charm tetraquarks within a diquark–antidiquark configuration. Using the perturbation theory, we estimate the masses of the heavy tetraquarks with hidden charm. Our present analysis suggests the charmonium-like states: X(3860), X(3872), , X(4140), and X(4700) can be accommodated in tetraquark picture. We particularly find that the may be treated as the first radial excitation of X(3872).
