本文报道了由BEDT-TTF [bis（ethylenedithio）tetrathiafulvalene]、一维[Fe（C_2O_4）Cl_（2-）]_n和溶剂CH_2Cl_2组成的电荷转移盐（1）的合成、晶体结构、拉曼光谱、导电性和磁性。在[（C2 H5）3 NH][Fe（C2 O 4）Cl 2]存在下，在CH 2Cl 2/CH 3OH溶液中电化学氧化中性BEDT-TTF产生1的晶体，其以三斜晶形式结晶。在1中，两个供体分子以面对面的方式堆叠为BEDT-TTF二聚体。BEDT-TTF二聚体在ab平面中形成（4，4）网格。（4，4）网格的空腔被两个CH 2Cl 2分子占据。施主层由[Fe（C2 O 4）Cl 2-]n阴离子片隔开，所述阴离子具有沿a轴沿着的Z字形链。给体之间存在S···S相互作用，给体与阴离子之间存在S···Cl相互作用。在χ与T的关系图上，在45 K附近观察到一个宽的最大值，表明低维系统中金属原子之间存在反铁磁相互作用。基于TTF核的键长和拉曼光谱，供体分子的形式电荷被指定为1.0+。该材料为半导体材料，σrt = 1.8 × 10 ~（-5）S/cm。
The synthesis, crystal structure, Raman spectra, conductivity, and magnetism of the title charge-transfer salt (1) composed of BEDT-TTF [bis(ethylenedithio)tetrathiafulvalene], one-dimensional [Fe(C2O4)Cl2–]n, and the solvent CH2Cl2, are described and interpreted. Electrochemical oxidation of neutral BEDT-TTF in the presence of [(C2H5)3NH][Fe(C2O4)Cl2] in a CH2Cl2/CH3OH solution yields crystals of 1, which crystallizes in triclinic form. In 1, two donor molecules stack in a face-to-face manner as a BEDT-TTF dimer. The BEDT-TTF dimers form a (4,4) grid in the ab plane. The cavity of the (4,4) grid is occupied by two CH2Cl2 molecules. The donor layers are separated by sheets of [Fe(C2O4)Cl2–]n anions with a zigzag chain along the a axis. There are S···S interactions between the donors, and S···Cl interactions between the donor and the anion. On the χ vs. T plot, a broad maximum is observed around 45 K, showing the existence of antiferromagnetic interactions between the metal atoms in the low-dimensional system. The formal charge of the donor molecules is assigned 1.0+ based on the bond lengths of the TTF core and on the Raman spectra. The material is a semiconductor with σrt = 1.8 × 10–5 S/cm.
