Abstract
The present work investigates the quasi-1D transport properties of the Ni(d mit)(2)-based compounds within a correlated, t-J model using the DMRG metho d. Strongly and weakly dimerized chains are studied by means of charge gap calculations (IP-EA) in order to extract the effective on-site repulsion te rm Li for the Ni(dmit)(2) molecule.
