crystal structures, thermal properties, and magnetic susceptibility. These salts are soluble in polar solvents such as methanol and water. The melting point of these compounds is affected by the dication following the order of triphenylphosphinium > pyridinium > imidazolium dications, and symmetrical dicationic salts > unsymmetrical ones. In these compounds, the trichloroferrate dianion exists in either
合成了新的(μ-氧代)双[三氯高铁酸盐(III)]阴离子型离子化合物,该化合物含有多种抗衡离子,并对其晶体结构,热性质和磁化率进行了表征。这些盐可溶于极性溶剂,例如甲醇和水。这些化合物的熔点受三苯基phosph>吡啶鎓>咪唑鎓二羧酸盐和对称两性盐>非对称盐的顺序影响。在这些化合物中,三氯高铁酸二阴离子以线性或弯曲形式存在,受指示影响。有趣的是,二价铁离子的化合物显示出的磁耦合常数比文献中报道的单阳离子为抗衡离子的二价铁盐的磁耦合常数小得多。此外,
