AB - The phase diagrams of isotropic and anisotropic triangular lattices with local Coulomb interactions are evaluated within cluster dynamical mean-field theory. As a result of partial geometric frustration in the anisotropic lattice, short-range correlations are shown to give rise to re-entrant behavior which is absent in the fully frustrated isotropic limit. The qualitative features of the phase diagrams including the critical temperatures are in good agreement with experimental data for the layered organic charge-transfer salts kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Cl and kappa-(BEDT-TTF)(2)Cu-2(CN)(3).
