We present a model description of the bound B19 isotope in terms of a B17-n-n three-body system where the two-body subsystems B17-n and n-n are unbound (virtual) states close to the unitary limit. The B19 ground state is well described in terms of two-body potentials only, and two low-lying resonances are predicted. Their eventual link with the Efimov physics is discussed. This model can be naturally used to describe the recently discovered resonant states in B20,21.
