The compound [Fe(tvp)(2)(NCS)(2)] . CH(3)OH, where tvp is 1,2-di-(4-pyridyl)-ethylene, has been synthesized and characterized by x-ray single-crystal diffraction. It consists of two perpendicular, two-dimensional networks organized in parallel stacks of sheets made up of edge-shared Fe(II) rhombuses. The fully interlocked networks define large square channels in the [001] direction. Variable-temperature magnetic susceptibility measurements and Mössbauer studies reveal that this compound shows low-spin to high-spin crossover behavior in the temperature range from 100 to 250 kelvin. The combined structural and magnetic characterization of this kind of compound is fundamental for the interpretation of the mechanism leading to the spin crossover, which is important in the development of electronic devices such as molecular switches.
[Fe(tvp)(2)(NCS)(2)]. CH(3)OH 的合成与晶体结构
通过 X 射线单晶衍射合成并表征了[Fe(tvp)(2)(NCS)(2)]. CH(3)OH，其中 tvp 是 1,2-二(4-吡啶基)乙烯。它由两个相互垂直的二维网络组成，这些网络平行堆积成由边共享的Fe(II)菱形组成的薄片。完全互锁的网络在[001]方向上定义了大的正方形通道。变温磁化率测量和穆斯堡尔研究表明，该化合物在 100 至 250 开尔文的温度范围内表现出低自旋到高自旋交叉行为。这种化合物的综合结构和磁性表征对于解释导致自旋交叉的机制是基础，这对于分子开关等电子设备的发展很重要。
