Iron(II) complexes of the pentadentate ligand N-methyl-N,N′,N′-tris(2-pyridylmethyl)ethane-1,2-diamine (L2) and the potentially hexadentate ligand N,N′-bis(6-methyl-2-pyridylmethyl)-N,N′-bis(2-pyridylmethyl)-N,N′-bis(2-pyridylmethyl)ethane-1,2-diamine (L1) have been isolated. Both ligands behave as pentadentate ligands in their iron(II) complexes with the general formulation [FeL(X)]n+(L = L1 or L2
五齿配体N-甲基-N,N ',N'-三(2-吡啶基甲基)乙烷-1,2-二胺(L 2)与潜在的六齿配体N,N'-双(II)的铁(II)配合物分离出6-甲基-2-吡啶基甲基)-N,N′-双(2-吡啶基甲基)-N,N′-双(2-吡啶基甲基)乙烷-1,2-二胺(L 1)。两种配体在其铁(II)配合物中均具有五齿配体,其通式为[FeL(X)] n +(L = L 1或L 2(n= 1或2),第六个配位位点(X)被辅助配体例如H 2 O,Cl,SCN或CN占据。[FeL 1(H 2 O)] [PF 6 ] 2 ·H 2 O 1的晶体结构表明,形式为六齿配体的6-甲基-2-吡啶基甲基之一的氮原子没有配位对铁原子。取而代之的是,水分子占据了第六个配位位置。络合物1在三斜空间群P中结晶,a = 10.485(2),b = 13.161(5),c= 14.853(6)Å,α= 69.31(4),β= 74.42(3),γ=
