interactions were observed between adjacent benzene rings within a cationic column. The temperature dependence of magnetic susceptibility measured in the temperature range of 1.8–330 K; indicates this compound is almost diamagnetic. The magnetic susceptibility was successfully modeled by a spin dimer magnetic exchange scheme with s = 1 2 to give rise to g =2.1, and the energy gap between singlet ground state and
摘要 一种离子对化合物,由具有 Λ 形(缩写为 [FBzPy] + )的 1-(4'-F-benzyl)pyridinium 和平面双(maleonitrileditholato)
钯(III)(缩写为 [Pd( mnt) 2 ] - ),已被合成和结构表征。该化合物中的阳离子和阴离子在固态下堆积成分离良好的柱子,相邻的阴离子在阴离子柱内存在强烈的二聚趋势,相邻的 Pd(III) 离子之间的接触交替为 3.39 和 4.06 A,分别。在阳离子柱内的相邻苯环之间观察到弱的 π⋯π 堆积相互作用。在1.8-330 K的温度范围内测量的磁化率的温度依赖性;表明该化合物几乎是抗磁性的。
