We discuss the interpretation of the open charm mesons D{sub s0}{sup *}(2317), D{sub s1}(2460) and the hidden charm meson X(3872) as hadron molecules. Using a phenomenological Lagrangian approach we consider strong and radiative decays of the D{sub s0}{sup *}(2317) and D{sub s1}(2460) states. The X(3872) is assumed to consist dominantly of molecular hadronic components with an additional small admixture of a charmonium configuration. A potential model based on meson-exchange is able to generate weak binding of the molecular hadronic components. The observed radiative ({gamma}J/{psi} and {gamma}{psi}(2s)) and strong (J/{psi}2{pi} and J/{psi}3{pi}) decays are shown to be consistent with the molecular structure assumption of the X(3872).
