The neutral complexes trans-[GeF4(PiPr3)2] and [GeF4(κ2-L)] (L = CH3C(CH2PPh2)3 or P(CH2CH2PPh2)3) are obtained from [GeF4(MeCN)2] and the ligand in CH2Cl2. Treatment of [GeF4(PMe3)2] with n equivalents of TMSOTf (Me3SiO3SCF3) leads to formation of the series [GeF4−n(PMe3)2(OTf)n] (n = 1, 2, 3), each of which contains six-coordinate Ge(IV) with trans PMe3 ligands and X-ray structural data confirm that
中性配合物反式-[GeF 4 (P i Pr 3 ) 2 ] 和 [GeF 4 (κ 2 -L)] (L = CH 3 C(CH 2 PPh 2 ) 3或 P(CH 2 CH 2 PPh 2 ) 3 ) 从[GeF 4 (MeCN) 2 ]和CH 2 Cl 2 中的
配体获得。[GeF 4 (PMe 3 ) 2 ] 用 n 当量的 TMSOTf (Me 3 SiO 3SCF 3 ) 导致形成系列 [GeF 4− n (PMe 3 ) 2 (OTf) n ] ( n = 1, 2, 3),每个系列都包含六配位的 Ge( IV ) 和反式PMe 3
配体和 X 射线结构数据证实 OTf 基团与 Ge( IV ) 有不同程度的相互作用。出乎意料的是,[GeF 3 (PMe 3 ) 2 (OTf)] 在溶液中发生还原脱
