An Organic Spin-Ladder Molecular Material

An Organic Spin-Ladder Molecular Material

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 wi...

Zusammenfassung: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.
