The independent 1:1 reactions of InNp3 (Np = CH2CMe3) and Ga(CH2SiMe3)3 with elemental selenium resulted in the formation of novel dimeric compounds with the general formula [R2M(μ-SeR)]2 (M = In, R = Np (1); M = Ga, R = CH2SiMe3 (2)) in a nearly quantitative yield. Reaction of GaMes3 (Mes = 2,4,6-Me3C6H2) with 2 mol of elemental Se, and subsequent addition of 4-picoline (C6H7N), resulted in the isolation of three compounds, [(Mes)C6H7N·Ga-μ-Se]2 (3), (Mes)2C6H7N·GaSeMes (4), and Se2MeS2. Compound 3 is a selenium-bridged dimer with two two-coordinate Se atoms and two 4-picoline (C6H7N) molecules in the dimeric unit. In related work, reaction of InNp3 with S2Ph2 afforded the dimeric compound [Np2In(μ-SPh)]2 (5) with elimination of NpSPh. The synthesis and characterization of 1-5, including their solid-state structures, are presented.
