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.%The crystals of [Fe（C12H8N2）3]（C6H6N2S2O6）·4H2O is triclinic system,space group P-1 with the cell parameters： 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.The Fe（Ⅲ） cation is in a slightly distorted octahedral geometry and is coordinated by six nitrogen atoms of three 1,10-phenanthroline molecules.There exits weak π-π stacking interactions between benzene ring of the 1,10-phenanthroline molecules from the adjacent molecules,and hydrogen bonds between the o-phenylendiamine-3,5-disulfonic and crystalwater molecules.It is the weak π-π stacking interactions and hydrogen bonds that extends the complex into a 2-D supermolecular structures.
