Abstract
For realistic triangular lattice of BEDT-TTF (hereafter ET) molecules with thereof dimerized κ-arrangement the electronic structure and the Fermi surface (FS) topology are obtained with emphasis of an intraET electron-electron correlations. Based on a symmetry of derived band structure, the nonspecified superconducting pairings of different symmetries are found. The binding state of electronic pair is evaluated in an empty lattice and the preferable d-pairing is found in the condensate with interplay between nodes of superconducting order parameter and properties of κ-ET2X salts. The obtained results are applicable for an analysis of specific heat, London penetration depth, NMR and baric measurements in ET2X compounds and related materials.
