Sumario:Using the vector exchange interaction in the local hidden gauge approach, which in the light quark sector generates the chiral Lagrangians and has produced realistic results for Ωc,\Xi c,\Xi b and the hidden charm pentaquark states, we study the meson-baryon interactions in the coupled channels that lead to the\Xi bb and Ω bbb excited states of the molecular type. We obtain seven states of the\Xi bb type with energies between and MeV, and one Ω bbb state at 15212 MeV.
