Treatment of iron(II) chloride or iron(II) bromide with 2 equiv of sodium quinaldate (qn = quinaldate or C10H6NO2−) yields the coordinatively unsaturated mononuclear iron(II) quinaldate complexes Na[FeII(qn)2Cl]·DMF and Na[FeII(qn)2Br]·DMF (DMF = N,N-dimethylformamide), respectively. When a similar synthesis is carried out using iron(II) triflate, a solvent-derived linear triiron(II) complex, [FeII3(qn)6(DMF)2]
用 2 当量的喹哪酸盐钠(qn = quinaldate 或 C 10 H 6 NO 2 -)处理氯化铁(II)或溴化铁(II)产生配位不饱和单核铁(II)喹那酸盐络合物 Na[Fe II (qn) 2 Cl]·DMF 和 Na[Fe II (qn) 2 Br]·DMF(DMF = N,N-二甲基甲酰胺)。当使用三氟甲磺酸铁 (II) 进行类似的合成时,溶剂衍生的线性三铁 (II) 络合物 [Fe II 3 (qn) 6 (DMF) 2],得到两个五配位铁(II)中心和一个六配位铁(II)中心。这些物种中的每一个都已使用 X 射线衍射进行了表征。这些配合物的振动特征与观察到的固态结构一致。这些化合物中的每一种都在 520 和 550 nm 之间显示出铁 (II) 到喹哪酸盐 (π*) 的电荷转移带。这些金属到配体的电荷转移带对喹哪酸盐的取代以及第一配位球配体的改变很敏感。然而,这些顺磁性高自旋铁
