摘要
利用3-甲氧基水杨醛、叠氮化钠与六水合氯化铁在室温下合成了一个新型单核铁配合物[Fe(hmb)2(N3)(H2O)],对其进行了X射线单晶衍射仪、元素分析测试。该配合物属于三斜晶系,P1空间群。晶胞参数:a=0.856 03(8)nm,b=0.958 54(9)nm,c=1.112 74(9)nm,α=78.957(7)°,β=87.317(7)°,γ=80.061(8)°。中心铁离子以六配位的模式与氧原子、氮原子连接形成八面体的构型,配合物分子首先通过C—H…N氢键连接成一维链状结构,进一步通过π…π共轭和氢键作用构成三维空间结构。
A new mononuclear iron complex was synthesized by 3-methoxy-2-hydroxy-benzaldehyde, sodium az-ide and iron chloride hexahydrate at room temperature, and was characterized by elemental analyses and X-ray single crystal diffraction.The complex belongs to the triclinic space group of P1 with a=0.856 03 （8） nm, b=0.958 54 （9） nm, c=1.112 74 （9） nm, α=78.957 （7）°, β=87.317 （7）°, γ=80.061 （8）°.The center iron is six-coordinated by oxygen atoms and nitrogen atoms and formed a octahedron geometry.The com-plex is firstly constructed by a 1D chain through C—H？N hydrogen bonds between intermolecules, and further builds a 3D network by π？πinteractions and hydrogen bonds between interchains.
