In the title compound, {[Fe(II)(C(8)H(4)N(2))(2)(H(2)O)(2)]Fe(III)Cl(4)·4CH(3)NO(2)}(n), the Fe(II) and Fe(III) ions are hexa- and tetra-coordinated, respectively. Each unique benzene-1,4-dicarbonitrile mol-ecule lies across a crystallographic inversion centre and bridges two Fe(II) ions (each situated on an inversion centre), generating two-dimensional (4,4) square grid layers. The tetra-chloridoferrate(III) anions and nitro-methane solvent mol-ecules lie between the square grid layers and are further link to the adjacent layers into a three-dimensional supra-molecular structure through O-H⋯Cl and O-H⋯O hydrogen bonds.
在标题化合物{[Fe(II)(C₈H₄N₂)₂(H₂O)₂][Fe(III)Cl₄]₂·4CH₃NO₂}ₙ中,Fe(II)和Fe(III)离子分别为六配位和四配位。每个独特的苯-1,4-二甲腈分子位于一个晶体学倒转中心上,并桥连两个Fe(II)离子(每个位于一个倒转中心上),生成二维(4,4)方形网格层。四氯合铁(III)阴离子和硝基甲烷溶剂分子位于方形网格层之间,并通过O-H⋯Cl和O-H⋯O氢键进一步连接相邻层形成三维超分子结构。
