title: Synthesis and characterization of well-defined aluminum-containing heterobimetallic selenides.
abstract: A series of novel aluminum heterobimetallic selenides were reported. The reaction of LAl(SeH)2 (1) with LiN(SiMe3)2 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(mu-Se)2GeMe2 (3), LAl(mu-Se)2GePh2 (4), LAl(mu-Se)2TiCp2 (5), and LAl(mu-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.
