In the present work, the possibility of the observed structure X(5568) or X(5616) as a hadronic molecule is investigated via its decay properties. Our estimations of the strong decay mode indicate that the hadronic molecule interpretation cannot be excluded since the determined parameter value is located in the empirical region. However, the unnatural large coupling constants indicate the molecular interpretation may be questionable. In addition, the radiative decays of the neutral partners of the X(5568) and X(5616) are estimated, which can be a test of the molecular interpretation in the future experiments.
