Pairs of stacks of organic donors D in the salt [(DT‐TTF) 2 ][Au(mnt) 2 ] (DT‐TTF = dithiophene‐tetrathiafulvalene, mnt = maleonitriledithiolate) form a classical ladder structure due to three close S … S interactions (see picture). Below 225 K the double stack of donor molecules forms a spin ladder with two legs, which arises through localization of unpaired electrons in the (DT‐TTF) 2 dimers.
