  In this work, we have calculated the mass spectra and decay properties of
dimesonic states in the variational scheme. The inter-mesonic interaction
considered as the Hellmann potential and One Pion Exchange potential. The mass
spectra of the $D\overline{D^{*}}$, $D^{*}\overline{D^{*}}$,
$D\overline{B^{*}}$, $B^{*}\overline{D}$, $B\overline{B^{*}}$,
$B^{*}\overline{B^{*}}$ bound states are calculated. The states X(3872),
$X_{2c}(4013)$, $Z_{b}(10610)/X_{b}$ and $Z_{b}(10650)/X_{b2}$ are compared
with $D\overline{D^{*}}$, $D^{*}\overline{D^{*}}$, $B\overline{B^{*}}$ and
$B^{*}\overline{B^{*}}$ dimesonic bound states. {\bf To probe the molecular
structure of the compared states, we have calculated the decay properties
sensitive to their long and short distance structure of the hadronic molecule.
The radiative decay for the state X(3872) into $J/\psi \gamma$ and $\psi(2S)
\gamma$ have been calculated and the ratio is found to be ten times lesser than
the experimental value whereas the other decay modes are comparable with other
theoretical and experimental results. This results restrict us to assigned the
pure molecular structure to the X(3872). But, Our results suggests that the
compared states are close to the molecular structure or have dominant molecular
component in their wave function. Apart from these, the other calculated mass
spectra of dimesonic states are predicted and for such bound states, the
experimental search are suggested.}
