Magnetic transitions of single-component molecular metal [Au(tmdt)2] and its alloy systems

J Am Chem Soc. 2006 Mar 29;128(12):3872-3. doi: 10.1021/ja0581144.

Abstract

A single-component molecular conductor [Au(tmdt)2] (tmdt = trimethylenetetrathiafulvalenedithiolate) undergoes an antiferromagnetic phase transition at unprecedentedly high temperature (TN = 110 K). Black microcrystals of alloys, [Ni1-xAux(tmdt)2] (0.0 < x < 1.0) were prepared. The Au-rich system exhibited an antiferromagnetic transition. Metallic single crystal was obtained for x = 0.25.
