The three pentaquark states,,and, discovered by the LHCb Collaboration in 2019, can be arranged into a complete heavy quark spin symmetry multiplet of hadronic molecules of. In the heavy quark mass limit, thebaryons can be related to the doubly charmed tetraquark states of isospin 1, i.e.,(,,), via heavy antiquark diquark symmetry, which dictates that theinteractions are the same as theinteractions up to heavy antiquark diquark symmetry breakings. In this work, we employ the contact-range effective field theory to systematically study thesystems, and we show the existence of a complete heavy quark spin symmetry multiplet of hadronic molecules composed of a doubly charmed tetraquark state and a charmed meson. These are a new kind of hadronic molecules and, if discovered, can lead to a better understanding of the many exotic hadrons discovered so far. In addition, we summarise the triply charmed hexaquark states formed by different combinations of hadrons. In particular, we show thatsystem can bind by the Coulomb force, which is analogous to a hydrogenlike atom.
