Abstract: We use QCD sum rules to investigate the nature of the meson X(3872), assumed to be a mixture between charmonium and exotic molecular c bar{q}[q\bar{c}]$ states with J^{PC}=1++. We compute the mass of the state, decay widths of the channels J/psi(npi) and J\psi\gamma, and the branching ratio for the production of the state in the decay B to X(3872)K. We find that the results are compatible with the experimental data for a small range for the values of the mixing angle, 5^\circ\leq\theta\leq13^\circ.
