The behavior of de Haas-van Alfven (dHvA) and Shubnikov-de Haas (ShdH) quantum oscillations in dual-layered quasi-two-dimensional organic metal (ET)HgBr(CHCl) is investigated. The oscillation spectra qualitatively agree with theoretical calculations of the bandgap structure. The angular dependence of the oscillation amplitude of magnetoresistance contains 'spin zeros'; the analysis of the location of these zeros allows one to evaluate the electron-phonon interaction constant: λ ≈ 0.2.
