In the title compound, {(C(12)H(12)N(2))[Fe(NCS)(4)]}(n), each Fe(II) cation is coordinated by four N-bonded and two S-bonded thio-cyanate anions in an octa-hedral coordination mode. The asymmetric unit consists of one Fe(II) cation, located on a center of inversion, as well as one protonated (E)-4,4'-(ethene-1,2-di-yl)dipyridinium dication and two thio-cyanate anions in general positions. The crystal structure consists of Fe-(NCS)(2)-Fe chains extending along the a axis, in which two further thio-cyanate anions are only terminally bonded via nitro-gen. Non-coordinating (E)-4,4'-(ethene-1,2-di-yl)dipyrid-inium cations are found between the chains.
在标题化合物{(C₁₂H₁₂N₂)[Fe(NCS)₄]}ₙ中,每个Fe(II)阳离子通过四个N键合和两个S键合的硫氰酸根阴离子以八面体配位模式配位。不对称单元由位于对称中心的一个Fe(II)阳离子、一个质子化的(E)-4,4'-(乙烯-1,2-二基)二吡啶鎓双阳离子以及处于一般位置的两个硫氰酸根阴离子组成。晶体结构由沿a轴延伸的Fe-(NCS)₂-Fe链组成,其中另外两个硫氰酸根阴离子仅通过氮末端键合。在这些链之间发现了非配位的(E)-4,4'-(乙烯-1,2-二基)二吡啶鎓阳离子。
