A single-component layered molecular conductor, [Au(ptdt)(2)] (ptdt: propylenedithiotetrathiafulvalenedithiolate) was prepared. Unlike the single-component molecular metal, [Au(tmdt)(2)] (tmdt: trimethylenetetrathiafulvalenedthiolate) exhibiting three-dimensional compact molecular packing and antiferromagnetic transition at 110 K, the compressed pellet of the microcrystals of [Au(ptdt)(2)] exhibited fairly high conductivity and small temperature-independent paramagnetic susceptibility.
