Abstrakt: The results of the investigations of Shubnikov-de Haas oscillations in the quasi-two-dimensional organic complexes (ET)${_8}$[ Hg4Cl12(C6H5Cl)2] , where X = CI, Br in the magnetic fields up to 40 T were reported. These results allow one to obtain some information about Fermi surface in the mentioned complexes. Shubnikov-de Haas oscillations in the compound with X = Cl correspond at least to two different cylindrical sheets of Fermi surface with the cross-section in (bc)-plane of 13% and 20% Brillouin zone cross-section. Shubnikov-de Haas oscillations in the complex with X = Br correspond to one cylindrical sheet with the cross-section in (bc)-plane of 13% of Brillouin zone cross-section. The experimental results for the complex with X = Br more agree with the theoretical calculations of Fermi surface than for the complex with X = Cl.
