Four iron complexes [PhN(CH2)2NH(SiMe3)]4FeLi·Et2O (1), [PhN(CH2)3NSiMe3]2FeLi(Et2O) (2), [PhN(CH2)2NCH(Ph)NSiMe3]2FeLi(Et2O)2 (3), and [PhN(CH2)3NCH(Ph)NSiMe3]2FeLi(Et2O)2 (4)} with polydentate nitrogen ligands were synthesized and structurally characterized by X-ray crystallography. The X-ray structures of complexes 1–4 show that they crystallize in three different systems. The magnetic properties
四种铁配合物 [PhN(CH2)2NH(SiMe3)]4FeLi·Et2O (1), [PhN(CH2)3NSiMe3]2FeLi(Et2O) (2), [PhN(CH2)2NCH(Ph)NSiMe3]2FeLi(Et2O) )2 (3) 和 [PhN(CH2)3NCH(Ph)NSiMe3]2FeLi(Et2O)2 (4)} 与多齿氮配体被合成并通过 X 射线晶体学进行结构表征。配合物 1-4 的 X 射线结构表明它们在三个不同的系统中结晶。研究了1-4的磁性。磁场强度的磁化趋势显示出Type-S曲线,说明1-4号配合物是超顺磁性的。
