采用水溶液法,合成了铁配合物[Fe(C12H8N2)3](C6H6N2S2O6).4H2O,该配合物晶体属三斜晶系,P-1空间群,晶胞参数是:a=12.8789(12),b=13.3808(13),c=14.859(2),α=104.558(2)°,β=100.780(2)°,γ=107.5760(10)°,V=2264.8(5)3,Z=2.铁离子周围有6个由1,10-邻菲罗啉提供的氮原子与之配位形成畸变的八面体的配位构型.相邻结构单元中的邻菲罗啉分子存在着弱的π-π堆积作用,没有参与配位的邻苯二胺-3,5-二磺酸根离子与结晶水分子通过氢键将配合物扩展为二维超分子结构.
Iron complex [Fe (C12H8N2) 3] (C6H6N2S2O6) .4H2O was synthesized by aqueous method. The crystal of this complex belongs to the triclinic system with P-1 space group and unit cell parameters of a = 12.8789 b = 13.3808 (13), c = 14.859 (2), α = 104.558 (2) °, β = 100.780 (2) °, γ = 107.5760 (10) °, V = 2264.8 (5) 3, Z = 2. Around the iron ions, there are six coordination structures of the nitrogen atoms provided by 1,10-phenanthroline to form distorted octahedron. The neighboring phenanthroline molecules have weak π -π stacking effect, the o-phenylenediamine-3,5-disulfonate ion and the crystal water molecules that did not participate in coordination extend the complex to a two-dimensional supramolecular structure through hydrogen bonding.
