Herein, the synthesis of new low-valent Group 14 phosphinidenide complexes [({SIDipp}P) M] exhibiting P-M pπ-pπ interactions (SIDipp=1,3-bis(2,6-diisopropylphenyl)-imidazolidin-2-ylidene, M=Ge, Sn, Pb), is presented. These compounds were investigated by means of structural, spectroscopic, and quantum-chemical methods. Furthermore, the monosubstituted compounds [(SIDippP)MX] (M=Sn, X=Cl; M=Pb, X=Br) are presented, which show dimeric structures instead of multiple bonding interaction.
本文介绍了新型低价第 14 族膦亚基配合物[({SIDipp}P)M]（其中 SIDipp=1,3-双(2,6-二异丙基苯基)-咪唑啉-2-亚基，M=Ge、Sn、Pb）的合成，这些配合物通过结构、光谱和量子化学方法进行了研究。此外，还介绍了单取代化合物[(SIDippP)MX]（M=Sn，X=Cl；M=Pb，X=Br），它们呈现出二聚体结构而不是多重键相互作用。
