Through the Born-Oppenheimer Approximation, we have performed a comprehensive investigation of the DD∗K, D*K, BB∗ and B* molecular states. In the framework of One-Pion Exchange model as well as the treatments of the coupled-channel eﬀects and S-D wave mixing, we find a loosely bound tri-meson molecular state these systems with the isospin configuration |0,, ±> and quantum number I(JP) = 1/2(1−), where the, is the total isospin of the three-body system, the 0 is the isospin of the D∗K, *K, B∗ and ∗. With the estimated error, the mass of the DD∗K or D∗K molecule is MeV or MeV. We also extend our calculations to the bottom sector and find tri-meson bound states for the BB∗ and B* with the mass MeV and MeV respectively.
