Scorpionate-Supported Dialkyl and Dihydride Lanthanide Complexes: Ligand- and Solvent-Dependent Cluster Hydride Formation

Non‐cyclopentadienyl lanthanide dihydrides [{(TpR,R′)LnH2}n] (R,R′=Me, n=4; R,R′=H, n=6) and [{(Tp Me 2)YH2}3(thf)2–3] were isolated and characterized. Their polynuclear frameworks are maintained in solution, and their nuclearity depends on the ligand and the solvent used in their preparation. The s...

Zusammenfassung:Non‐cyclopentadienyl lanthanide dihydrides [{(TpR,R′)LnH2}n] (R,R′=Me, n=4; R,R′=H, n=6) and [{(Tp Me 2)YH2}3(thf)2–3] were isolated and characterized. Their polynuclear frameworks are maintained in solution, and their nuclearity depends on the ligand and the solvent used in their preparation. The structure of [{(Tp Me 2)YH2}4] is shown (B red, H white, N blue, Y orange). TpR,R′=tris(3‐R‐5‐R′‐pyrazolyl)borate.
