Deprotonation of the yttrium–arsine complex [Cp′ 3 Y{As(H) 2 Mes}] ( 1 ) (Cp′=η 5 ‐C 5 H 4 Me, Mes=mesityl) by n BuLi produces the μ‐arsenide complex [{Cp′ 2 Y[μ‐As(H)Mes]} 3 ] ( 2 ). Deprotonation of the AsH bonds in 2 by n BuLi produces [Li(thf) 4 ] 2 [{Cp′ 2 Y(μ 3 ‐AsMes)} 3 Li], [Li(thf) 4 ] 2 [ 3 ], in which the dianion 3 contains the first example of an arsinidene ligand in rare‐earth metal chemistry. The molecular structures of the arsine, arsenide, and arsinidene complexes are described, and the yttrium–arsenic bonding is analyzed by density functional theory.
