摘要：

Treatment of SmI2.2THF with 2 equiv of NaHB(3,5-Me2pz)3 in THF affords purple Sm[HB(3,5-Me2pz)3]2, 1, in high yield. Despite its insoluble nature, 1 readily reacts with azobenzene to give soluble, green Sm[HB(3,5-Me2PZ)3]2(N2Ph2), 2. The structures of 1 and 2 have been determined by X-ray crystallography. Complex 1 has the symmetrical metallocene structure. The eta3-bonding mode of both pyrazolylborate ligands is retained in 2, and in addition the cis-azobenzene moiety is symmetrically bonded to the samarium center via both nitrogen atoms.
