Popis:	Grafting of the bis(phosphinimino)methanide complex [La{CH(PPh2NSiMe3)2}{N(SiHMe2)2}2] (1) onto dehydroxylated silica (SiO2-700) affords material 2. Full characterization of this material by infrared spectroscopy, elemental analysis, and multinuclear, multidimensional solid-state NMR spectroscopy showed formation of well-defined bis(phosphinimino)methanide amido surface species, [(≡SiO)La{CH(PPh2NSiMe3)2}{N(SiHMe2)2}], along with [≡SiOSiHMe2] sites.
