摘要：

The kappa-ET(2)X compounds are classified as strongly correlated electron systems. The tight-binding approach for correlated electrons is applied to the kappa-ET(2)X family. The electronic spectrum and density of states are calculated. The singlet superconducting pairing of different symmetries is studied based on the symmetry of the lattice model of ET(2)-layer, and the superconducting coupling constants are calculated. The comparison of the theoretical speculations with available experimental data is made for normal and superconducting phases in kappa-ET(2)X.
