摘要：

The reaction of (C5H4(t)Bu2)2Sm with AlH3 in ether or (C5H4(t)Bu2)2Sm.THF with AlH3 in THF in the presence of excess of TMEDA and pentane involves the oxidation of Sm(2 +) to Sm(3+), partial loss of Cp"-ligands and formation of the octanuclear complex Cp5"Sm4(AlH4)3.2Me2NC2H4NMe2, the cyclic metal core of which resembles a sitting frog. Atoms Sm1, Sm3 and Sm4 are coordinated with one Cp"-ligand each, while Sm2 is bonded with two Cp"-ligands. All metals of the complex are bonded by mu-2- and mu-3-bridging hydrogens.
