resulted in the formation of [LAl(SeLi)2(THF)2] (2) (L = HC(CMeNAr)2, Ar = 2,6-iPr2C6H3). Compound 2 reacted
with Me2GeCl2, Ph2GeCl2, Cp2TiCl2, and Cp2ZrCl2, respectively, to produce LAl(μ-Se)2GeMe2 (3), LAl(μ-Se)2GePh2
(4), LAl(μ-Se)2TiCp2 (5), and LAl(μ-Se)2ZrCp2 (6) in moderate yields. Compounds 2−6 were characterized by elemental
analysis, NMR, and electron impact-MS. The X-ray single-crystal structure of 3 is reported and confirms the spirocyclic
arrangement of the aluminum atom within the six-membered AlN2C3 and four-membered AlSe2Ge rings.
