摘要：

The synthesis and chemistry of monoligand lanthanide dihydrides, LLnH(2), is a very active current area of research. Herein we summarize the status of our contributions utilizing various scorpionates, Tp(R,R'), as protective ancillary ligands and show that the nuclearity of the so obtained hydride clusters depends on the size of the scorpionate ligands and, in one instance, the solvent used in the synthesis. Following brief consideration of the synthesis of the various precursor dialkyl complexes, (Tp(R,R'))Ln(CH2SiMe3)(2)(THF)(1/0), the solid-state structures of the hydride clusters, [(Tp(R,R'))LnH(2)](n) (R, R' = Me, Ln = Nd, Sm, Y, Yb and Lu, n = 4; R, R' = H, Ln = Y, Yb and Lu, n = 6; R, R' = Pr-i, Ln = Y and Lu, n = 3), obtained via hydrogenolysis, are described.
