The nature of superconductivity in planar organics is still a controversial problem. We investigate theoretically d-wave and anisotropic s-wave pairing in k-(BEDT-TTF)2X compounds. Assuming strong dimerization, we consider a single band model with elliptical Fermi surface to calculate density of states, specific heat and spin susceptibility as functions of temperature. The obtained results, compared with experiments, should help to resolve the question of pairing symmetry.
