Notes:
Sm[N(SiMe3)2]2(thf)2 reacts with 1,1,3,3-tetramethyldisilazane by a transsilylamination reaction to form the hexane-soluble Sm[N(SiHMe2)2]2(thf)x in high yield. An X-ray diffraction study reveals a novel trinuclear complex of composition Sm{[μ-N(SiHMe2)2]2Sm[N(SiHMe2)2](thf)}2 featuring a bent array of metal centers. Multiple metal···SiH β-agostic interactions sterically and electronically saturate the samarium(II) centers implying a new coordination mode of the bridging amide ligands.
