We analyze the relation between a model recently proposed to describe Co doped Au chains with four-fold symmetric leads, and the generalized SU(2)×SU(2) Anderson model. We compare the structure of the Kondo limit in the general case. We calculate the spectral density and the conductance as a function of temperature in both cases, showing that both models display similar non-Fermi liquid behavior.
