资源简介：
The monoanionic phosphine(phosphinimino)methanide ligand (Ph2PCHPPh2NSiMe3)- is
introduced in organometallic chemistry. Starting from the established compound Ph2PCH2PPh2NSiMe3 (1) the potassium salt [K(Ph2PCHPPh2NSiMe3)]n (2) was prepared. The solid
state structure of 2 shows a η3-N−P−C heteroallyl coordination of the ligand as well as a
π-coordination of the phenyl rings to the potassium atoms. These coordination modes lead
to an infinite chain in the solid state. Compound 2 was further reacted to the samarium
complex [(η5-C5Me5)2Sm(Ph2PCHPPh2NSiMe3)], in which the (Ph2PCHPPh2NSiMe3)- ligand
coordinates in η3-heteroallylic fashion via the N atom and the methine group to the center
metal.
