A dual-functional organic-inorganic hybrid (BEDT-TTF)Cu(HCOO) () (BEDT-TTF=bis(ethylenedithio)tetrathiafulvalene) was obtained through the electrochemical oxidation of neutral BEDT-TTF in the presence of an ammonium salt of the one-dimensional copper-formate framework [(CH)NH]Cu(HCOO) in a CHCl-CHOH solution. Compound was composed of organic donor BEDT-TTF⋅ in a θ-phase arrangement and Jahn-Teller distorted (4,4) grid anion sheets [Cu(HCOO)] with 1/2. We identified the material as a semiconductor with values of =10 S cm. The anion sheet is a coordination isomer of [Cu(HCOO)] and, compared with the starting material, shows antiferromagnetic behavior as the well-known inorganic Cu-O, Co-O square layers for creating inorganic conducting magnets. Long-range antiferromagnetic ordering was observed at 8.0 K.
通过在CHCl-CHOH溶液中,在一维甲酸铜骨架[(CH)NH]Cu(HCOO)的铵盐存在下,对中性双(乙撑二硫)四硫富瓦烯(BEDT-TTF)进行电化学氧化,得到了一种双功能有机-无机杂化材料(BEDT-TTF)Cu(HCOO) (BEDT-TTF = 双(乙撑二硫)四硫富瓦烯)。化合物由处于θ相排列的有机供体BEDT-TTF⋅和具有1/2的Jahn-Teller畸变(4,4)网格阴离子片[Cu(HCOO)]组成。我们将该材料鉴定为一种半导体,其电导率值为10 S cm。阴离子片是[Cu(HCOO)] 的配位异构体,与起始材料相比,表现出反铁磁行为,就像众所周知的用于制造无机导电磁体的无机Cu-O、Co-O方形层一样。在8.0 K时观察到长程反铁磁有序。
