The novel phosphonyl-substituted ferrocene derivatives [Fe(η(5) -Cp)(η(5) -C5 H3 {P(O)(O-iPr)2 }2 -1,2)] (Fc(1,2) ) and [Fe{η(5) -C5 H4 P(O)(O-iPr)2 }2 ] (Fc(1,1') ) react with SnCl2 , SnCl4 , and SnPh2 Cl2 , giving the corresponding complexes [(Fc(1,2) )2 SnCl][SnCl3 ] (1), [{(Fc(1,1') )SnCl2 }n ] (2), [(Fc(1,1') )SnCl4 ] (3), [{(Fc(1,1') )SnPh2 Cl2 }n ] (4), and [(Fc(1,2) )SnCl4 ] (5), respectively. The compounds are characterized by elemental analyses, (1) H, (13) C, (31) P, (119) Sn NMR and IR spectroscopy, (31) P and (119) Sn CP-MAS NMR spectroscopy, cyclovoltammetry, electrospray ionization mass spectrometry, and single-crystal as well as powder X-ray diffraction analyses. The experimental work is accompanied by DFT calculations, which help to shed light on the origin for the different reaction behavior of Fc(1,1') and Fc(1,2) towards tin(II) chloride.
新型膦酰基取代的二茂铁衍生物[Fe(η(5)-Cp)(η(5)-C5H3{P(O)(O-iPr)2}2-1,2)] (Fc(1,2))和[Fe{η(5)-C5H4P(O)(O-iPr)2}2] (Fc(1,1'))与SnCl2、SnCl4和SnPh2Cl2反应，分别生成相应的配合物[(Fc(1,2))2SnCl][SnCl3] (1)、[{(Fc(1,1'))SnCl2}n] (2)、[(Fc(1,1'))SnCl4] (3)、[{(Fc(1,1'))SnPh2Cl2}n] (4)和[(Fc(1,2))SnCl4] (5)。这些化合物通过元素分析、(1)H、(13)C、(31)P、(119)Sn核磁共振和红外光谱、(31)P和(119)Sn交叉极化魔角旋转核磁共振光谱、循环伏安法、电喷雾电离质谱以及单晶和粉末X射线衍射分析进行表征。实验工作还伴有密度泛函理论计算，这有助于阐明Fc(1,1')和Fc(1,2)对氯化锡(II)不同反应行为的起源。
