We investigate hadronic molecular states with the quark contents ccqqs, bbqqs, and bcqqs (q=u, d) by employing the extended local hidden gauge approach. Considering that the S-wave meson-baryon interactions are dominated by vector meson exchange, the coupled channels scattering amplitudes are obtained by solving the Bethe-Salpeter equation in its on-shell form. We find that the poles appearing on the complex Riemann sheet are potential candidates for dynamically generated molecular pentaquark states. The results suggest the existence of a total of fourteen molecular states with quantum numbers I (J^P) =0 (1/2^-), 0 (3/2^-), and 0 (5/2^-), which arise from the interactions of the K^ (*) Ξ₂₂^ (*), K^ (*) Ξ₁₁^ (*), K^ (*) Ξ₁₂^ (*), and K^ (*) Ξ₁₂^' channels, respectively. Their binding energies are calculated to be about 0. 1-33 MeV, and this range depends on the free parameter of the theory. Our research contributes to the spectroscopic studies of hadronic molecular pentaquark states.
