在氯苯 - 乙醇溶液中，在一维甲酸铜框架[(C₂H₅)₃NH]₂Cu₂(HCOO)₅的铵盐存在下，通过中性双（乙烯二硫代）四硫富瓦烯（BEDT - TTF）的电化学氧化，得到了一种双功能有机 - 无机杂化物(BEDT - TTF)₂Cu₂(HCOO)₅（1）。化合物1由θ相排列的有机给体BEDT - TTF⁺⁰⋅⁵和具有S = 1/2的杨 - 特勒畸变（4,4）网格阴离子片[Cu₂(HCOO)₅⁻]ₙ组成。我们确定该材料为一种半导体，其在300K时的电导率σ为10⁻¹ S cm⁻¹。阴离子片是[Cu₂(HCOO)₅⁻]ₙ的一种配位异构体，并且与起始材料相比，表现出反铁磁行为，就像用于制造无机导电磁体的著名的无机Cu - O、Co - O方形层一样。在8.0 K时观察到长程反铁磁有序。
A dual‐functional organic–inorganic hybrid (BEDT‐TTF)2Cu2(HCOO)5 (1) (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 [(C2H5)3NH]2Cu2(HCOO)5 in a C6H5Cl–C2H5OH solution. Compound 1 was composed of organic donor BEDT‐TTF+0⋅5 in a θ‐phase arrangement and Jahn–Teller distorted (4,4) grid anion sheets [Cu2(HCOO)5 ‐]n with S=1/2. We identified the material as a semiconductor with values of σ 300K=10−1 S cm−1. The anion sheet is a coordination isomer of [Cu2(HCOO)5 ‐]n 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.
