An Electron‐Transfer Ferromagnet with <i>T</i>_c=107 K Based on a Three‐Dimensional [Ru₂]₂/TCNQ System

Abstract

Electron-transfer makes a magnet: 2:1 assembly of [Ru2II,IIL4] paddlewheel complexes and BDTA-TCNQ yielded a new structural type of electron-transfer system with a three-dimensional network structure which exhibits a long-range ferromagnetic transition at Tc=107 K (see depicted χ vs T curve and inset view of structure along the a axis). L=m-fluorobenzoate, BTDA-TCNQ=bis(1,2,5-thiadiazolo)tetracyanoquinodimethane.
